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.

Deployment
The software uses the Arduino framework and the development environment of PlatformIO, which offers better tools than the Arduino IDE.
- Upload the configuration file to the board:
pio run -t uploadfs- Compile the project
pio run -t compile- Upload firmware
pio run -t upload
