Homeostasis

Homeostasis

Temperature, air humidity and soil humidity sensor that communicates via MQTT. The project is implemented using a Wemos D1 mini board with the following components:

DHT22 temperature and humidity sensor
FC-28 soil hygrometer sensor
Battery shield
3.7V 1000mAh Lithium battery

The sensor captures the data every 15 minutes and sends it to a MQTT broker and then enters deep sleep, it is important to save power as the device runs off a battery.

Dependencies

Deployment

The software uses the Arduino framework and the development environment of PlatformIO, which offers better tools than the Arduino IDE.
