My goal is to build a device for measuring water quality in rivers.

some time back I implemented a river monitoring system using The Things UNO with a BMP280 temperature/pressure sensor, a SR04M ultrasonic transducer and a DS18B20 DallasTemperature sensor uploading data over LoRaWAN to the myDevices/cayenne desktop

I was reading the sensors and uploading data every 10 minutes

you can see the river is tidal – rise and fall of about 10cm

also experimented with turbidity, pH and DO sensors
