Battery Voltage description: The battery for the lse01 should be between 3.0V to 3.6V. If we need to use a battery less than 3.3 volts we have to remove diode D1 and shortcut the two pads of it.Diode D1 lays between the main circuit and the battery If battery is less than 2.7 volts user have to replace the battery. text/html 2023-01-05T14:38:56+00:00 Anonymous (anonymous@undisclosed.example.com) https://student-wiki.eolab.de/doku.php?id=eolab:treemap:start&rev=1672925936&do=diff TreeMap Kamp-Lintfort Collecting Sensor Data with LoRa and MQTT To monitor the soil moisture content of a few selected trees in the LaGa area in Kamp-Lintfort, we installed some dragino Lse01 LoRa sensors. The sensors send their data via LoRa to an Imst Gateway located on top of the old winding tower, which then forwards the data to a chirpstack server. Since the server has an integrated MQTT-Broker, we can use the MQTT node in node-red to get our data and save it to an influx database.…
