This is my first try of an round case for my Wemos D1 mini. I just fixed it with hotglue and put a little capton tape between sensor an ESP8266.
Model has 3
...Show more ventilation slits, a hole for reaching the reset button and 2 holes for screws on the bottom part.
The top part holds by friction and you can turn the DHT22 in every position.
Be sure to put your ESP8266 in sleep oder deepsleep mode. Otherwise it could became warm and gives you a little off temperatur readings from DHT22.
