ESP12E (NodeMCU, ESP8266) + Si7021Print

After my experimentes with NodeMCU and SHT75 I designed next version of my mini meteostation.

I designed own PCB for plastic box. I chose the same ESP8266 module which is in NodeMCU, ESP12E.
SHT75 temperature/humidity sensor is expensive (but very accurate), so I chose another temperature/humidity sensor. Si7021 by Silicon Labs company.
