+===Collecting Sensor Data with LoRa and MQTT===
+{{ :eolab:treemap:img_20210610_151102.jpg?200 |}}
+To monitor the soil moisture content of a few selected trees in the LaGa area in Kamp-Lintfort, we installed some [[https://www.dragino.com/products/lora-lorawan-end-node/item/159-lse01.html|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. You can find a guide on how to set up the node here:
+[[https://github.com/hschoofs/chirpstack_integrations/tree/main/example_code/mqtt_node_red|node-red MQTT setup with TLS.]] \\
+The data is displayed on a [[https://weather.eolab.de/grafana/d/-QK3uw3Mz/laga-lse01?orgId=1&refresh=30m|Grafana dashboard]].
