LoRa Node Applications

Aerated Wastewater Treatment System (AWTS)

I currently use one of my Nodes to monitor the pressure in the aeration line and the water level in the main influent tank of an aerated wastewater treatment system.

See MPS20N0040D Air Pressure Sensor and AJ-SR04M Ultrasonic Distance Sensor for hardware configuration details.

Place the AWTS Node sketch folder in the Arduino IDE root folder (Arduino). If running on a Heltec CubeCell Plus module, as is currently configured, this sketch also requires the latest version of the Heltec [CubeCell] hardware support libraries.

Weather Station

This is not currently a 'complete' weather station, as the Node is only taking 'real' weather readings from a [Davis 6466M] rain gauge (yes, I would prefer to have the rain collector further away from the pole—see photo above—but it has been said that life is a compromise...) and [Davis 6410] anemometer. The BME280 sensor is currently only measuring temperature, humidity & pressure inside the Node enclosure, which sits in direct sunlight (for the benefit of the solar panel)—at some point I'll get it out into something that more reasonably approximates a Stevenson screen.

See Davis 6466/6466M Rain Collector and Davis 6410 Anemometer for hardware configuration details.

Place the Weather Node sketch folder in the Arduino IDE root folder (Arduino). If running on a Heltec CubeCell Plus module, as is currently configured, this sketch also requires the latest version of the Heltec [CubeCell] hardware support libraries.
