Logger Components and Operation

Start/Stop Button: Press this button for 3 seconds to start or stop logging data, or to resume logging on the next even logging interval. This requires configuring the logger in the app with a push button start or stop, and with Allow Button Restart selected (see Configuring the Logger). You can also press this button for 1 second to record an internal event (see Logger Events), to silence a beeping alarm (see Setting up Alarms), or to turn the LCD screen on if the option to turn off the LCD has been enabled (see Configuring the Logger).
Press both the Start/Stop button and the Alarm/Stats button simultaneously for 3 seconds to reset a logger password.
Alarm/Stats Button: Press this button for 1 second to switch between statistics, alarm readings, and the current sensor readings as applicable or to silence a beeping alarm. Press this button for 3 seconds to clear a visual alarm if the logger is configured in the app to maintain the visual alarm until the alarm button is pressed (see Setting up Alarms).

• Mounting Loops: Use the two mounting loops (only one visible in the diagram) to mount the logger with the hook-and-loop strap (see Mounting the Logger).
• Temperature Sensor: This sensor is located in the lower left corner of the raised panel to the right of the LCD screen.
• RH Sensor: This sensor is located behind the vented panel in the logger case to the right of the LCD screen and the temperature sensor.
• LCD Screen: This logger is equipped with an LCD screen that displays details about the current status. This example shows all symbols illuminated on the LCD screen followed by definitions of each symbol in the table on the next page.

Notes:

• You can disable the LCD screen when logging. Deselect “Show LCD” when setting up the logger as described in the next section. When this option is disabled, you can still temporarily view the LCD screen by pushing the Start/Stop button for 1 second. The LCD remains on for 10 minutes.
• The LCD screen refreshes every 15 seconds regardless of the logging interval selected in the app. If you choose a logging interval less than 15 seconds, the data is recorded at the faster interval, but the sensor readings are updated on the screen only every 15 seconds.
• When the logger has stopped logging, the LCD screen remains on and displays “STOP” until the logger is offloaded to your mobile device (unless the logger is configured with the “Show LCD” option disabled). Once the logger has been offloaded, the LCD turns off automatically after 2 hours. The LCD turns back on the next time the logger connects with your device through the app.
• The LCD screen flashes “HELLO” when you page the logger from the app (see Downloading the App and Connecting to a Logger).
• The LCD screen flashes “CHIRP OFF” when an audible alarm is cleared.

Downloading the App and Connecting to a Logger
Install the app to connect to and work with the logger.

1. Download the app. Download HOBOconnect to a phone or tablet from the App Store® or Google Play™ or download the app to a Windows computer from www.onsetcomp.com/products/software/hoboconnect
2. Install the batteries. Open the battery door on the back of the logger and insert two AAA batteries observing polarity (see Battery Information). Reinsert the battery door and snap it back into place.
3. open the app. Enable Bluetooth in your device settings if prompted.
4. connect to the logger. Tap Devices and then tap the logger tile in the app to connect to it.

If the logger does not appear or if it is having trouble connecting, follow these tips:

• Make sure the logger is within range of your mobile device or computer. The range for successful wireless communication is approximately 30.5 m (100 ft) with full line-of-sight.
• If your device can connect to the logger intermittently or loses its connection, move closer to the logger, within sight if possible.
• If the logger appears in the app, but you cannot connect to it, close the app and then power down your device to force the previous Bluetooth connection to close.

Once the logger is connected, you can:

Configuring the Logger
Use the app to set up the logger, including setting alarms, selecting the options to start and stop logging, and choosing a logging mode. These steps provide an overview of setting up the logger. For complete details, see the HOBOconnect User Guide.

1. In the app, tap Devices and then tap the logger tile to connect to it.
2. Tap Configure & Start to configure the logger.
3. Tap Name and type a name for the logger (optional). If you do not enter a name, the app uses logger serial number as the name.
4. Tap Group to add the logger to a group (optional).
5. Tap Logging Interval and choose how frequently the logger will record data unless operating in burst logging mode (see Burst Logging).
6. Tap Start Logging and select when logging begins:
   • On Save. Logging begins immediately after configuration settings are saved.
   • On Next Interval. Logging begins at the next even interval as determined by the selected logging interval.
   • On Button Push. Logging begins when you press either the Start/Stop logging button on the logger for 3 seconds or start logging with the app.
   • On Date/Time. Logging begins at a date and time you specify. Select the Date and Time.
7. Tap Stop Logging and specify when logging ends.
   • Never Stop (Overwrites Old Data). The logger does not stop at any predetermined time. The logger continues recording data indefinitely, with newest data overwriting the oldest.
   • On Date/Time. The logger stops logging on a specific date and time that you specify.
   • After. Select this if you want to control how long the logger should continue logging once it starts. Choose the amount of time you want the logger to log data. For example, select 30 days if you want the logger to log data for 30 days after logging begins.
   • Stop When Memory Fills. The logger continues recording data until the memory is full.
8. Tap Pause Options, then select Pause On Button Push to specify that you can pause the logger by pressing its button for 3 seconds. Select Allow Button Resume to specify that you can press the Start/Stop button on the logger to resume logging.
   Important: When you select Allow Button Resume and you use the Start/Stop button on the logger to stop and restart logging, logging restarts on the next even logging interval, not at the time you pushed the button. For example, a logger started logging at 7:00 AM with a logging interval set to 1 hour. If you press the Start/Stop button to stop the logger at 8:45 AM and then press the button again at 10:15 AM, logging will not begin immediately at 10:15 AM. Instead, logging will begin again at 11:00 AM, which is the next even interval time based on your 1-hour logging interval. Depending on the logging interval, the gap between the time you press the button to resume logging and the time actual logging begins could be significant. The faster the logging interval, the less time elapses before logging resumes.
9. Tap Logging Mode. Select either fixed or burst logging. With fixed logging, the logger records data for all enabled sensors and/or selected statistics at the logging interval selected
   (see Statistics Logging for details on choosing statistics options). In burst mode, logging occurs at a different interval when a specified condition is met. See Burst Logging for more information.
10. Enable or disable Show LCD, which controls whether the LCD on the logger remains illuminated while the logger is logging. If you disable Show LCD, the LCD on the logger does not show the current reading, status, or other information while the logger is logging. You can temporarily turn the LCD screen on by pressing the Start/Stop button on the logger for 1 second. In addition, you can always view the status of any in-range logger on your mobile device regardless of the logger’s LCD setting (may require a logger password as applicable).
11. Select the sensor measurement types that you want to log. By default, both the temperature and RH sensors are enabled. Both sensors are required to calculate dew point, which is an additional data series available for plotting after downloading data from the logger. You can also set up alarms to trip when a sensor reading rises above or falls below a specified value. See Setting up Alarms for details on enabling sensor alarms and selecting the associated audible and visual alarm settings.
12. Select whether to upload data to HOBOlink® via the gateway or the app (optional and requires an active HOBOlink account).
13. Tap Start to save the configuration settings.
    Logging begins based on the settings you selected. Press the start button on the logger if you set it up to start logging with a button push. Deploy the logger using the mounting materials (see Mounting the Logger). After logging begins, you can read out the logger at any time (see Reading Out the Logger for details).

Setting up Alarms
You can set an alarm to trip on the logger when a sensor reading rises above or falls below a specified value. This alerts you to problems so you can take corrective action. To set an alarm:

1. Tap Devices.
2. Tap the logger tile in the app to connect to it and tap Configure & Start.
3. Tap a Sensor/Channel.
4. Tap Enable Logging, if necessary.
5. Tap Alarms to open that area of the screen.
6. Select Low if you want an alarm to trip when the sensor reading falls below the low alarm value. Enter a value to set the low alarm value.
7. Select High if you want an alarm to trip when the sensor reading rises above the high alarm value. Enter a value to set the high alarm value.
8. For the Duration, select how much time should elapse before the alarm trips and select one of the following:
   • Cumulative Samples. The alarm trips once the sensor reading is out of the acceptable range for the selected duration any time during logging. For example, if the high alarm is set to 85°F and the duration is set to 30 minutes, then the alarm trips once the sensor readings have been above 85°F for a total of 30 minutes since the logger was configured.
   • Consecutive Samples. The alarm trips once the sensor reading is out of the acceptable range continuously for the selected duration. For example, the high alarm is set to 85°F and the duration is set to 30 minutes, then the alarm trips only if all sensor readings are 85°F or above for a continuous 30-minute period.
9. Repeat steps 2–8 for the other sensor.
10. In the Alarm Settings area, enable Audible Alarm if you want a beep to sound on the logger every 30 seconds when the sensor alarm trips. The beeping continues until you clear the alarm in the app, press either button on the top of the logger, or 7 days have passed. Battery life is slightly reduced when this setting is enabled. It is recommended that you enable this feature only if you have regular access to the logger so that you can easily turn off the beeping.
11. For Show Visual Alarms Until, select one of the following options to determine how long the alarm icon remains illuminated on the logger LCD screen after an alarm trips:
    • Logger Reconfigured. The alarm icon remains visible on the LCD until the next time the logger is reconfigured.
    • Sensor in Limits. The alarm icon remains visible on the LCD until the sensor reading returns to the normal range between any configured high and low alarm limits.
    • Alarm Button Pressed. The alarm icon remains visible until you press the Alarm/Stats button on the logger.

Notes

• The alarm icon is illuminated on the logger LCD when the alarm trips. You can also press the Alarms/Stats button on the logger to view the farthest out-of-range value during the deployment. The logger checks alarm limits when the logger’s LCD screen refreshes every 15 seconds.
• The actual values for the high and low alarm limits are set to the closest value supported by the logger. In addition, alarms can trip or clear when the sensor reading is within the resolution specifications. This means the value that triggers the alarm may differ slightly from the value entered.
• When you download data from the logger, alarm events can be displayed on the plot or in the data file. See Logger Events.
• Once cleared, an audible alarm starts beeping again if the sensor values go out of the normal range. Even if an audible alarm is cleared, a visual alarm may remain on the logger LCD and in the app depending on the settings selected for maintaining visual alarms or because the alarm condition may still be in effect. In addition, an audible alarm continues beeping when the sensor values have returned to the normal range until it is cleared as described in step 10.
• Although an audible alarm and a visual alarm can occur at the same time when a sensor alarm is tripped, they are cleared in different ways. The audible alarm can be cleared as described in step 10. Meanwhile, a visual alarm is cleared as determined by the setting selected for Maintain Visual Alarm Until configuration setting. This means you could clear a beeping audible alarm and the visual alarm remains on the LCD and in the app until the logger is reconfigured, the sensor is in limits, or the alarm button is pressed—depending on the setting you selected.
• If the logger is configured to stop logging with a button push, any tripped alarms are cleared automatically when logging is stopped and no Alarm Cleared event is logged. This ensures that the logger starts checking for alarm conditions when logging resumes (if the logger was configured with Allow Button Resume selected).

Burst Logging
Burst logging is a logging mode that allows you to set up more frequent logging when a specified condition is met. For example, a logger is recording data at a 5-minute logging interval and burst logging is configured to log every 30 seconds when the temperature rises above 85°F (the high limit) or falls below 32°F (the low limit). This means the logger records data every 5 minutes as long as the temperature remains between 85°F and 32°F. Once the temperature rises above 85°F, the logger switches to the faster logging rate and records data every 30 seconds until the temperature falls back to 85°F. At that time, logging then resumes every 5 minutes at the fixed logging interval. Similarly, if the temperature falls below 32°F, then the logger switches to burst logging mode again and record data every 30 seconds. Once the temperature rises back to 32°F, the logger then returns to fixed mode, logging every 5 minutes. Note: Sensor alarms, statistics, and the Stop Logging option Never Stop (Overwrites Old Data) are not available in burst logging mode.

To set up burst logging

1. Tap Devices. Press the Start/Stop button on the logger to wake it up, if necessary.
2. Tap the logger tile in the app to connect to the logger and tap Configure & Start.
3. Tap Logging Mode and then tap Burst Logging.
4.  Set the burst logging interval, which must be faster than the logging interval. Keep in mind that the faster the burst logging rate, the greater the impact on battery life and the shorter the logging duration. Because measurements are being taken at the burst logging interval throughout the deployment, the battery usage is similar to what it would be if you had selected this rate for the normal logging interval.
5. Select Low and/or High and type a value to set the low and/or high values.
6. Repeat step 5 for the other sensor if desired.

Notes

• The high and low burst limits are checked only when the logger’s LCD screen refreshes once every 15 seconds. If you set the logging interval to less than 15 seconds and the sensor reading falls outside the levels, burst logging does not begin until the next 15-second refresh cycle.
• If high and/or low limits are configured for more than one sensor, burst logging begins when any high or low condition goes out of range. Burst logging does not end until all conditions on all sensors are back within normal ranges.
• The actual values for the burst logging limits are set to the closest value supported by the logger.
• Burst logging mode can begin or end when the sensor reading is within the resolution specifications. This means the value that triggers burst logging may differ slightly from the value entered.
• Once the high or low condition clears, the logging interval time is calculated using the last recorded data point in burst logging mode, not the last data point recorded in fixed mode. For example, a logger has a 10-minute logging interval and logs a data point at 9:05. Then, the high limit is surpassed and burst logging begins at 9:06. Burst logging then continues until 9:12 when the sensor reading falls back below the high limit. Now back in fixed mode, the next logging interval is 10 minutes from the last burst logging point, or 9:22 in this case. If burst logging had not occurred, the next data point would have been at 9:15.
• A New Interval event is created each time the logger enters or exits burst logging mode. See Logger Events for details on plotting and viewing the event. In addition, if the logger is stopped with a button push while in burst logging mode, a New Interval event is automatically logged and the burst condition is cleared, even if the actual high or low condition has not cleared. The logger checks the high and low conditions when logging resumes (if the logger is configured with Allow Button Resume selected).

Statistics Logging
During fixed logging, the logger records data for enabled sensors and/or selected statistics at the logging interval selected. Statistics are calculated at a sampling rate you specify with the results for the sampling period recorded at each logging interval. You can log the following statistics for each sensor:

•  The maximum, or highest, sampled value,
• The minimum, or lowest, sampled value,
• An average of all sampled values, and
• The standard deviation from the average for all sampled values.

For example, a logger is configured with both the temperature and RH sensors enabled, and the logging interval set to 5 minutes. The logger is set to Fixed Logging Mode and all four statistics are enabled and with a statistics sampling interval of 30 seconds. Once logging begins, the logger measures and records the actual temperature and RH sensor values every 5 minutes. In addition, the logger takes a temperature and RH sample every 30 seconds and temporarily stores them in memory. The logger then calculates the maximum, minimum, average, and standard deviation using the samples gathered over the previous 5-minute period and logs the resulting values. When downloading data from the logger, this results in 10 data series (not including any derived series, such as dew point): two sensor series (with temperature and RH data logged every 5 minutes) plus eight maximum, minimum, average, and standard deviation series (four for temperature and four for RH with values calculated and logged every 5 minutes based on the 30-second sampling).

To log statistics

1. Tap Devices. Press the Start/Stop button on the logger to wake it up, if necessary.
2. Tap the logger tile in the app to connect to it and tap Configure & Start.
3. Tap Logging Mode and select Fixed Logging Mode.
4. Tap to turn on Statistics.
   Note: Fixed Logging Mode records sensor measurements taken at each logging interval. The selections you make in the Statistics section add measurements to the recorded data.
5. Select the statistics you want the logger to record at each logging interval: Maximum, Minimum, Average, and Standard Deviation (average is automatically enabled when selecting Standard Deviation). Statistics are logged for all enabled sensors. In addition, the more statistics you record, the shorter the logger duration and the more memory is required.
6. Enter a value in Statistics Sampling Interval to use for calculating statistics. The rate must be less than, and a factor of, the logging interval. For example, if the logging interval is 1 minute and you select 5 seconds for the sampling rate, the logger takes 12 sample readings between each logging interval (one sample every 5 seconds for a minute) and use the 12 samples to record the resulting statistics at each 1-minute logging interval. Note that the faster the sampling rate, the greater the impact on battery life. Because measurements are being taken at the statistics sampling interval throughout the deployment, the battery usage is similar to what it would be if you had selected this rate for the normal logging interval.

Once logging begins, click the Alarm/Stats button on the logger to cycle through the current maximum, minimum, average, and standard deviation data on the LCD screen. Note that the logger always displays the current sensor readings in the app even if they are not being logged. You can plot the statistics series once you read out the logger.

Setting a Password
You can create an encrypted password for the logger that is required if another device attempts to connect to it. This is recommended to ensure that a deployed logger is not mistakenly stopped or purposely altered by others. This password uses a proprietary encryption algorithm that changes with every connection.

To set a password

1. Tap Devices. Press the Start/Stop button on the logger to wake it up, if necessary. Tap the logger tile in the app to connect to it.
2. Tap Lock Logger.
3. Type a password and then tap Set.

Only the device used to set the password can then connect to the logger without entering a password; all other devices are required to enter the password. For example, if you set the password for the logger with your tablet and then try to connect to the logger later with your phone, you must enter the password on the phone but not with your tablet. Similarly, if others attempt to connect to the logger with different devices, they are also required to enter the password. To reset a password, press the circle on the logger for 10 seconds or connect to the logger and tap Manage Password and tap Reset.

Downloading Data From the Logger

To download data from the logger

1. Tap Devices. Press the Start/Stop button on the logger to wake it up, if necessary. Tap the logger tile in the app to connect to the logger.
2. Tap Download Data. The logger downloads data to the phone, tablet, or computer.
3. Once the download is complete, tap Done to return to the previous page or tap Export and Share to save the file in the specified format.
4. When the export file has successfully been created, tap Done to return to the previous page or tap Share to use your device’s usual modes of sharing.

You can also upload data automatically to HOBOlink, Onset’s web-based software, using the app or the MX gateway. For details, see the HOBOconnect User Guide and see the HOBOlink help for details on working with data in HOBOlink.

Logger Events
The logger records the following internal events to track logger operation and status. You can view events in exported files or plot events in the app.

To plot events, tap HOBO Files and select a file to open.

Tap (if applicable) and tap . Select the events you want to plot and tap OK.

Mounting the Logger
There are several ways to mount the logger using the materials included:

• Use the four magnets on the back of the logger case to mount it to a magnetic surface.
• Attach Command strips to the back of the logger to mount it a wall or other flat surface. Double up the two Command strips so that they protrude past the magnets.
• Use the double-sided tape to affix the logger to a surface.
• Insert the hook-and-loop strap through the mounting loops on both sides of the logger to mount it to a curved surface, such as a pipe or tubing.

Protecting the Logger
The logger is designed for indoor use and can be permanently damaged by corrosion if it gets wet. Protect it from condensation. If the message FAIL CLK appears on the LCD screen, there was a failure with the internal logger clock possibly due to condensation. Remove the battery immediately and dry the circuit board.
Note: Static electricity may cause the logger to stop logging. The logger has been tested to 8 KV, but avoid electrostatic discharge by grounding yourself to protect the logger. For more information, search for “static discharge” on onsetcomp.com

Battery Information
The logger requires two user-replaceable AAA 1.5 V alkaline or optional lithium batteries for operation at the extreme ends of the logger operating range. Expected battery life varies based on the ambient temperature where the logger is deployed, the logging or sampling interval, frequency of offloading and connection to the mobile device, number of channels that are active, audible alarms duration, use of burst mode or statistics logging, and battery performance. New batteries typically last 1 year with logging intervals greater than 1 minute. Deployments in extremely cold or hot temperatures, a logging interval faster than 1 minute, or a sampling interval faster than 15 seconds can impact battery life. Estimates are not guaranteed due to uncertainties in initial battery conditions and operating environment.
Note: Make sure the batteries installed have flat negative terminals. There should be no indent in the bottom of the batteries. Batteries with indents in the negative terminals may become loose and prevent proper operation.

To install or replace the batteries

1. Open the battery door on the back of the logger.
2. Remove any old batteries.
3. Insert two new batteries observing polarity.
4. Reinsert the battery door and snap it back into place.

WARNING: Do not cut open, incinerate, heat above 85°C (185°F), or recharge the lithium batteries. The batteries may explode if the logger is exposed to extreme heat or conditions that could damage or destroy the battery case. Do not dispose of the logger or batteries in fire. Do not expose the contents of the batteries to water. Dispose of the batteries according to local regulations for lithium batteries.
