Arduino sketch that monitors an Aerogarden. It captures temperature, humidity, light intensity and the water tank level, and sends the data to Thingsboard using MQTT.
Sensors:
- DHT21 (AM2301) temperature/humidity
- BH1750 light sensor
- Water level sensor
It runs on a NodeMCU v3 (ESP8266 12E) board.
Measurements are taken once every minute.
