WS32-ETH01 Cover

This is a remix from makerbotschmidtienet´s "WT32-ETH01 CO2 Sensor"

i removed the gap for the co2 sensor to use this case with an WT32 ETH01 and only
4 cables (RX, TX, Gnd, 5V) for UART connection to my grid tie inverter.

It fits perfect and the connection is more stable than with an ESP8266
