This is an MQTT based Temperature & Humidity sensor I designed for my own purposes in order to track the status of the various rooms in my house. This was so I could better understand my heating and dehumidification requirements especially over winter by integrating it's data into Home Assistant.

The built in software will enable you to configure the device to use your own Wifi network and MQTT broker.

By default it will come with the better DHT22 sensor that has a temperature range of -40 to 125 degrees Celsius (+- 0.5 degrees accuracy) and a Humidity range of 0 to 100% (+- 2% to 5% accuracy).

If however you don't need that range or accuracy then you can opt to have a DHT11 sensor which has a temperature range from 0 to 50 degrees Celsius (+-2 degrees accuracy) and humidity range of 20% to 80% (+-5% accuracy).
