Slim Case for ESP8266 / LoLin NodeMcu plus DHT 22 with Airflow

This is an improved Version of my first design of the case. It has got air in- and outlets to prevent the DHT-22 from makeing incorrect reads because of the heat from the ESP.

I additionally recommend to programm the ESP to go into deepsleep mode after transmitting the data. This will also reduce the heat of the ESP and thus let the DHT-22 read more precisely.
