ESP Thermometer

thingiverse

I've designed this Indoor case for my ESP32 Based Thermometer. I have printed a lot of them. One for each room at home. This is the third version which can screwed together. Changing Battery will be easy now. The outer diameter is 60 mm and the inner socket about 58 mm. It has a M58x1.5 thread. You screw them together. The thermometer itself is based on an Espressif ESP32 and a Bosch BME280. It will measure Temperature, Humidity, Air Pressure and Battery Voltage. All Values will be pushed by MQTT to my Homeassistant.

I can also provide a full partlist and my Sourcecode as OpenSource if somebody is interested :)
