* 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 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
- [[https://github.com/adafruit/DHT-sensor-library][Adafruit DHT sensor library]]
- [[https://github.com/adafruit/Adafruit_Sensor][Adafruit Unified Sensor Driver]]
- [[https://github.com/knolleary/pubsubclient][PubSubClient]]
