This is an enclosure for a Temperature / Humidity display running on Lolin D1 Mini, powered by 4xAA batteries and using DHT-22 for measuring temperature/humidity.
There is a guide on how I did this build available in my blog: https://blog.tperamaki.com/part-1-temperature-humidity-display/
The guide also has the code for running the thing, which includes features such as posting the data to a localhost server for usage with for example HomeKit.
