WIRELESS EXTERNAL PROBE TEMP SENSOR
1. QUICK START
To start using your sensor, simply go to: https://console.radiobridge.com From here you can register your device and immediately start receiving messages. The sensor configuration, message monitoring, and setting up alerts is usually self-explanatory through the user interface. For further explanations of any sensor features, you may refer to this user guide
2. OVERVIEW
2.1. Sensor Overview
The wireless sensors designed and manufactured by Radio Bridge provide full sensor to cloud solutions for Internet of Things (IoT) applications. The external probe temperature sensor measures temperature using an external temperature probe. If the temperature rises above or falls below the configured thresholds, an alert is sent over the wireless network. Temperature is sampled every 15 seconds and averaged over 1 minute. Thus, the sensor is not appropriate for applications that need to detect rapid changes in temperature within periods of less than a minute. The temperature has been calibrated with controlled temperature chambers, and is accurate to +/- 1 degree C.
Features include: · Built-in radio that talks directly with LoRaWAN wireless networks · Two types of tamper detection: enclosure tamper and wall mount tamper
o Enclosure tamper detects if the packaging of the sensor itself is opened or broken Available on the RBSx01, RBSx05, and RBSx06 sensors.
o Wall mount tamper detects if the sensor has been removed from the wall or mounting point. Available on the RBSx01 and RBSx05 sensors.
· 200,000+ transmissions on a single battery and a 5-10 year battery life depending on usage. See Battery section for more detail.
· Fully integrated internal antenna · Over the air sensor configuration in the field · Automatic low battery reporting and supervisory messages

4. BATTERY LIFE
This device uses a lithium non-rechargeable battery and is capable of 200,000+ total messages depending on the wireless standard and usage. For an accurate estimate of battery life, please refer to the "Sensor Battery Estimator.xlsx" spreadsheet on the Radio Bridge website. This spreadsheet combines usage information such as average number of messages per day and estimates the battery life for a particular device.
Refer to the spreadsheet "Sensor Battery Estimator.xlsx" on the Radio Bridge website for specific battery life estimates.
The power required for a message transmission is much greater than the "sleep current" (the power consumed when the device is inactive) for high power radio technologies such as LoRaWAN. This means that the battery life for most devices is primarily dependent on the number of transmissions per day. Different battery types will deplete over time with different voltage profiles. For instance, a lithium battery will maintain a relatively high voltage for the life of the battery and then experience a rapid drop near the end, whereas an alkaline battery will experience a more gradual reduction in voltage over time. Radio Bridge devices are shipped with lithium batteries, and these are recommended when the battery needs to be eventually replaced. Temperature also plays a role in battery life. The battery life estimates in the online spreadsheet assume room temperature, but temperatures close to the maximum and minimum ratings will have a negative impact on battery life. For example, battery voltage tends to be lower in cold temperatures and the internal circuitry needs a certain minimum voltage to operate properly before it will shut down. Thus, battery life will tend to be shorter when running the device in cold environments.
Battery voltage will be lower in cold temperatures and thus battery life will be reduced in cold environments.
The battery voltage is reported by the supervisory messages as well as a low battery indicator. See the section on Message Protocol for more detail.

5. TEST MESSAGES
The device can be triggered to send test messages by placing a magnet next to the side of the enclosure. The location of the magnet is indicated by the triangular notch on the side of RBSx01 and RBSx05 sensors. RBSx04 sensors do not have this capability. There is a small magnetic Hall effect sensor that will detect the presence of a magnet and send a message. This can be used for diagnostic purposes to ensure the sensor is within range and connected to the network.
6. MESSAGE PROTOCOL
This section defines the protocol and message definitions for the device.
Radio Bridge provides a web-based console at console.radiobridge.com to configure and monitor devices. Usage of this console is highly recommended for most customers rather than implementing the protocols defined in this section.

If the standard Radio Bridge console (console.radiobridge.com) is not used, refer to this section to decode the device data and configure the device through downlink messages.
6.1. Common Messages
There are common messages across all wireless devices that are defined in the document "Common Sensor Messages" which is available on the Radio Bridge website.
Refer to the document "Common Sensor Messages" for definitions of all common messages. Common messages are not defined in this document.

Common messages include basic error messages, tamper, supervisory, and downlink ack. It is important to refer to that document prior to decoding the messages defined in this section.

WIRELESS EXTERNAL PROBE TEMP SENSOR
When a temperature is out of range, it will be reported as 0x7f (highest positive signed number) on the high end and 0x80 on the low end.

6.3. Downlink Messages
The downlink message (web application to sensor) specific to the sensor configuration is defined in following table. The common downlink messages are not included in this section (see common messages document).
Table 7 Downlink Configuration Message 0x09
Byte Description 0 Mode: 0x00 for Threshold, or 0x01 for Report on Change 1-6 Defined by Mode (See Mode sections)
The mode byte selects one of two modes: threshold based alerts or report-on-change alerts. The remainder of the payload (bytes 1-6) are determined by the mode selected and defined in the next two sections.

6.3.1.

Threshold Mode
Threshold mode is set when byte 0 of the payload is set to 0x00. The remainder of the payload is defined in the following table.

Table 8 Downlink Configuration Message for Threshold Mode
Byte Description 0 0x00 (Threshold mode) 1 Periodic reporting in 1 minute or 1 hour intervals. Default is 0 (disabled) 2 Restoral margin (bits 3:0 only). Default 5 degrees C. 3 Lower temperature threshold. Default 10 degrees C. 4 Upper temperature threshold. Default 90 degrees C.

PAGE 8 OF 14

WIRELESS EXTERNAL PROBE TEMP SENSOR
The upper and lower temperature thresholds are signed values with units of one degree Celsius (range is -40 to 100 degrees C). Note that if the configuration settings exceed the maximum ratings on the sensor, the sensor may not report an event.
The Restoral Margin is used for the upper and lower thresholds and requires the temperature value to cross back over the threshold a certain amount before a new event is reported. This prevents excessive event messages if the temperature is at or near the threshold.
For example, consider an upper temp threshold set at 30 degrees Celsius and the restoral margin set at 5 degrees. If the temperature initially exceeds 30 degrees then an event is generated and a message is sent to the network. The temperature must now drop to 25 degrees and then exceed 30 degrees before another event is reported.
The restoral margins are unsigned values with units of 1 degree Celsius (range is 1-15 degrees C). If a restoral margin is set to 0, it is disabled.
Periodic reporting is described in the section Periodic Reports.

6.3.2.

Report on Change Mode
Report on Change mode is set when byte 0 of the payload is set to 0x01. The remainder of the payload is defined in the following table.

Table 9 Downlink Configuration Message for Report on Change Mode
Byte Description 0 0x01 (Report on Change mode) 1 Periodic reporting in 1 minute or 1 hour intervals. Default is 0 (disabled) 2 Not used 3 Temperature increase 4 Temperature decrease

If the temperature increase or decrease are non-zero, then the sensor will send an alert any time the temperature changes by the specified amount. For example, if the temperature increase and decrease are set to 5 degrees, then an alert is sent every time the temperature changes 5 degrees from the last report. The temperature increase and decrease are unsigned values with units in degrees C.
Periodic reporting is described in the section Periodic Reports.

6.3.3.

Periodic Reports
The temperature sensor can also send periodic updates, and this is defined in byte 1 of both modes. A setting of 0 will disable periodic reporting. The period is defined in 1 hour increments when the most significant bit is 0, and it is defined in 1 minute increments when the most significant bit is 1 as shown in the following table.

Table 10 Period Bye (byte 1) from Downlink Configuration Message

Bit 7 Bits 6:0

Period defined in hours (1-127 hours)

Period defined in minutes (1-127 minutes)

For example, to receive a report every 4 hours, byte 1 would be set to 0x04. To receive a periodic report every 15 minutes, byte 1 would be set to 0x8f.
Note that prior to firmware version 1.3, only hourly reporting is available. The firmware version can be found in the reset message and is logged on the Radio Bridge console.

Periodic reporting is not recommended as it will increase data service fees and significantly reduce battery life. Wherever possible, use thresholds or report-on-change only.
