The nodes communicate using novel LoRaWAN technology. LoRa communication is an excellent candidate to realize such distributed monitoring applications. With its long range capabilities and low power characteristics it is ideal for the current monitoring setup.
Sensor data from our nodes are sent from below ground, inside sewer manholes and retention tanks to a LoRa gateway located on a roof of a public building. Gateway and network server infrastructure is operated by Loriot.io.
Visualization of sensor data, data export and data access run on our cloud infrastructure. We are looking forward to see first results from the field tests in the near future.
