To mantain the best climatic condition for a reptile needs alot of experience and especially if you are, like me, a newby it’s better to help yourself with the proper technology.
For this reason I’ve designed a very simple MQTT enabled sensor able to be rapidly integrated with your domotic system or simply used as standalone temperature and humidity monitor.
It’s based upon a very simple circuit where a DH22 sensor is connected to an ESP32 controller, the data collected by the sensor are both sent to an MQTT server (configurable) and an Oled display.
Connection is very simple:

The ESP32 could be easily flashed using Arduino
