User Manual 6 Device Installation Installing Sensor Node 6.1.1 Installing the Sensor Node Bracket Specially designed for installing SenseCAP Sensor Nodes, the bracket consists of a bracket and a sliding cap. With designated screw-holes, the bracket helps fasten the Sensor Node firmly onto a pole or a wall. 1) To install on a pole, you can use zip ties to fasten the bracket (recommended pole dimension is 5070mm in diameter). Please refer to the following image for bracket directions.
User Manual surface. 6.1.2 Installing Sensor Nodes After installing brackets, let’s install sensors. 1) The Sensor Probe should be placed vertically downward with the label facing outward. Be consistent with the bracket gap. Make sure the circle part in the middle of Sensor Node is aligned with the middle of the bracket, and then press the Sensor Node to fit into the bracket. A click/snap sound indicates that the Sensor Node has been installed successfully.
User Manual 6.1.3 Dos and Don’ts in Installing Sensor Probes The same instruction applies to installing the different Sensor Nodes. However, there are some tips to keep in mind when installing certain Sensor Nodes. ⚫ Light Sensor The Sensor Probe of the Light Sensor needs to be placed vertically upward, and there should not be anything obstructing sunlight from the Sensor Probe. ⚫ CO2 Sensor The Sensor Probe can be fastened with self-drilling screws.
User Manual 7 Trouble Shooting Sensor Node not join the network, how to do? 1. Check the gateway channels configuration. Make sure the gateway and Sensor Node have the same uplink and downlink channels. 2. Check the gateway real-time log and RESET the sensor to see if there are any sensor data packets. If there are packets, check whether the gateway is sending downlink packets. 3.
