Button: Push this button for 1 second to illuminate the LCD or 3 seconds for the mote to search for a HOBOnet Wireless Sensor Network to join (see Adding the Mote to the HOBOnet Wireless Sensor Network). LCD Screen: The mote is equipped with an LCD screen that displays details about the current status. The following example shows all symbols illuminated on the LCD screen followed by definitions of each symbol in the table. LCD Symbol Description The battery indicator shows the approximate battery charge remaining. This is a signal strength indicator. The more bars, the stronger the signal between motes. If there is no x icon next to the signal strength indicator, then the mote is part of a HOBOnet Wireless Sensor Network. An empty signal strength icon plus the x icon indicates that the mote is not currently part of a network. See Adding the Mote to the HOBOnet Wireless Sensor Network for details on how to add a mote to the network. When the mote is in the process of joining a network, the signal strength icon will blink and then the bars in the icon will cycle from left to right. The x icon will blink during the last step in the network registration process (see Adding the Mote to the HOBOnet Wireless Sensor Network for details). This indicates a problem with the sensor itself (the mote is operational). Check the sensor and make any adjustments to it as needed. Contact Onset Technical Support if the problem persists. HOBOnet Water Level Sensor Interface User Guide Adding the Mote to the HOBOnet Wireless Sensor Network The mote must join a HOBOnet Wireless Sensor Network before it can begin measuring water level and transmitting data. This requires that you have access to the RX Station and the mote at the same time; we recommend that you complete these steps before deploying the mote. Important: If you are setting up a new RX Station, follow the instructions in the station quick start before setting up this mote (go to www.onsetcomp.com/support/manuals/24380man-rx2105-rx2106-qsg for RX2105 and RX2106 stations or go to www.onsetcomp.com/support/manuals/18254-MAN-QSGRX3000 for RX3000 stations).

This signal strength icon blinks while the mote searches for a network. c. Once the mote finds a network, the icon stops flashing. The bars cycle from left to right. d. This network connection "x" icon blinks while the mote completes the registration process, which may take up to five minutes. Once the mote has finished joining the network, the "x" icon disappears and the channel count on the station LCD increases by the total channel count for that sensor model. The green LED blinks quickly while the mote searches for a network to join and then blinks slowly while it completes the network registration. Once the mote has finished joining the network, the green LED turns off and the blue LED then blinks indefinitely while the mote is part of the network. Note: If the mote cannot find the network or has trouble remaining connected during this process, make sure the mote is in a vertical, upright position and within range of the station. 8. Press the Search button (the magnifying glass) on the station to stop searching for motes. HOBOnet Water Level Sensor Interface User Guide Mounting and Positioning the Sensor Node · Position the sensor node towards the sun, making sure the solar panel is oriented so that it receives optimal sunlight throughout each season. You may need to periodically adjust the position of the sensor node as the path of the sunlight changes throughout the year or if tree and leaf growth alters the amount of sunlight reaching the solar panel. · Make sure the sensor node is mounted a minimum of 1.8 m (6 feet) from the ground or vegetation to help maximize distance and signal strength. · Consider using plastic poles such as PVC to mount the sensor node as certain types of metal could decrease the signal strength. · Place the sensor node so there is full line of sight with the next sensor node. Use a repeater if there is an obstruction between sensor nodes. · There should not be more than five sensor nodes in any direction from a repeater or the manager. Data from sensor nodes travels or "hops" across the network and may not reach the station if the sensor node is more than five hops away. Deploying the Water Level Sensor Warning: Do not suspend anything from the 6-foot cable. The 6-foot cable is not designed to support the weight of the direct-read cable and sensor. 6-foot cable Press this button again to stop searching for motes. If you added more than one more mote to the network, then the total channel count on the station LCD for the manager module represents all measurement channels plus a battery channel for each mote in the network. Sensor measurements are recorded at the logging interval specified in HOBOlink, transmitted to the station, and uploaded to HOBOlink at the next connection interval (readout).

Deploy the water level sensor in water and secure it in position (for example, hang it in a well). HOBOnet Water Level Sensor Interface User Guide Figure 1: Water level is below reference point Figure 2: Water level is above reference point Figure 3: Water level is above pressure sensor *The Multiplier represents the density of the water, which is a function of its salinity. This is equal to 1 divided by the true density of the water in g/cm3 (e.g., 1/1.025 for typical salt water). General Guidelines · The absolute pressure sensor in the water level sensor is temperature compensated over the range of 0° to 40°C (32° to 104°F). The barometric pressure sensor is temperature compensated over the range of -20° to 50°C (-4° to 122°F). To obtain the highest level of accuracy, both the sensor and station should be allowed to come to full temperature equilibrium (approximately 20 minutes) before the reference level is entered in HOBOlink as described in Setting up the Station. · Sudden temperature changes should be avoided. · When deploying the water level sensor in a well, make sure the well is vented to the atmosphere. Typically, a small hole can be drilled in the side of the well cap to ensure that the pressure inside and outside the well is at equilibrium. Use the Onset well cap (WELL-CAP-02) if it is a 5 cm (2 inch) well. Otherwise, you will need to find another method of attaching the cable at the top of your well so that the sensor stays in position. The sensor cable includes a Kevlar® strength member so it can support the weight of the sensor and its cable. You can attach a clamp around the cable, such as a hose clamp, but be careful not to damage the cable. · There is a vent for the barometric sensor on the back of the mote. This vent must not collect water or it will block proper barometric pressure readings. The best way to avoid water collecting is to mount the station vertically. · The sensor face located in the nose cone of the sensor end needs to be in the water to measure water level. U.S. and International Sales: 1-508-759-9500 7 www.onsetcomp.com Make sure the sensor face (represented by dashed lines in this diagram) is in the water to measure water level 10.0 mm (0.39 in.) · Any change in length of the sensor cable will result in a 1to-1 corresponding error in the depth measurement. Always pull-test a cable prior to deploying a sensor in a well to make sure it does not stretch. · If you are deploying the sensor in a lake, river, or stream, you must first build a stilling well to protect it and the cable. A simple stilling well can be constructed with PVC or ABS pipe. A properly constructed stilling well holds the sensor in position and protects the sensor from currents, wave action, and debris. Suspend the sensor in the stilling well so it is always underwater, but not on the bottom to be buried by silt. For more information, see the Technical Application Note for How to Build a Stilling Well at: https://www.onsetcomp.com/resources/tech-notes/howto-build-stilling-well · To prevent the sensor from moving in currents and to ensure the support cable is kept straight during deployment, you may need to add a weight to the suspension cable just above the sensor or hang a weight below the sensor. In some cases, you may need to both add a weight and use a stilling well. · Be very careful not to exceed the burst pressure for the sensor. The pressure sensor will burst if the maximum depth is exceeded (see Specifications). The sensor should be positioned at a depth where it will remain in the water for the duration of the deployment, but not exceed the rated bursting depth. · If the cable is too long, loop the cable and secure the cable with multiple zip ties to ensure the loop does not slip. The looped cable should be tight enough that the cable can be easily pulled out of the well if necessary, but it must not bend the cable any tighter than a 1.25 cm (0.5 inch) radius to prevent damage to the cable.

Eject the storage device from the computer and disconnect the cable from the mote. The firmware installation process will begin automatically on the mote. The blue LED will blink rapidly while the firmware is installed. Once the firmware installation is complete, the LCD symbols return and the mote will automatically rejoin the network. Notes: · Mac® users: A message may appear indicating the disk has not ejected properly when disconnecting the mote from the computer. The mote is operational and you can ignore the message. · If the blue LED turns off abruptly while copying the file or installing the firmware, a problem has occurred. Contact Onset Technical Support for help. Battery Information The mote uses two 1.2 V rechargeable NiMH batteries, charged by the built-in solar panel. The quality and quantity of solar light can affect whether the battery is sufficiently charged to last through the night and cloudy periods. Make sure the mote is placed in a location that will receive several hours of sunlight each day. If the mote does not receive enough sunlight to recharge the batteries, the battery life is estimated at 34 months. When batteries are regularly recharged, expected battery life is estimated at 35 years. Battery life varies based on the ambient temperature where the mote is deployed, the logging interval, the number of tripped alarms, and other factors. Deployments in extremely cold or hot temperatures can impact battery life. Estimates are not guaranteed due to uncertainties in initial battery conditions and operating environment. Mote operation will stop when battery voltage drops to 1.8 V. Mote operation will return if the battery recharges to 2.3 V. If the batteries are unable to be recharged, replace them with fresh rechargeable batteries. Note: if you install used rechargeable batteries that together are less than 2.3 V, the mote will not resume operation. U.S. and International Sales: 1-508-759-9500 8 www.onsetcomp.com To replace rechargeable batteries: 1. Open the mote door. 2. Remove the old batteries and install fresh ones observing polarity. 3. Make sure the solar panel cable is plugged in. Make sure solar panel cable is installed when using rechargeable batteries The mote contacts the network once the new batteries are installed. The green LED blinks during this process while the bars in the signal strength indicator on the LCD cycle from left to right and then the x icon blinks. Once this process is complete, the x icon is removed, the green LED stops blinking, and the blue LED begins blinking instead. Lithium Batteries You can use two 1.5 V lithium batteries (HWSB-LI) for operation at the extreme ends of the mote operating range. Lithium battery life is an estimated at 1 year, but varies based on the ambient temperature where the mote is deployed, the logging interval, the number of tripped alarms, and other factors. Estimates are not guaranteed due to uncertainties in initial battery conditions and operating environment. When using lithium batteries, you must disconnect the solar panel cable because the batteries will not be recharged. To install lithium batteries: 1. Open the mote door. 2. Remove any old batteries and install the new ones observing polarity. 3. Push in the side tab of the solar panel cable connector and pull the connector out of the cable port. 4. Place the connector in the slot on the inside of the mote door. Make sure the solar panel cables are tucked inside the door so that they do not interfere with the interior seal when the mote is closed. HOBOnet Water Level Sensor Interface User Guide Store the solar panel connector here when using lithium batteries The mote contacts the network once the new batteries are installed. The green LED blinks quickly while the mote searches for a network to join and then blinks slowly while it completes the network registration. Once the mote has finished joining the network, the green LED turns off and the blue LED then blinks indefinitely while the mote is part of the network. WARNING: Do not cut open, incinerate, heat above 85°C (185°F), or recharge the lithium batteries. The batteries may explode if the mote is exposed to extreme heat or conditions that could damage or destroy the battery cases. Do not mix battery types, either by chemistry or age; batteries may rupture or explode. 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.
