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 addons:

  • DHT11 temperature and humidity
  • 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 that the Arduino IDE
