  License: This code is public domain but you buy me a beer if you use this and we meet someday (Beerware license).

  Uses the HTU21D library to display the current humidity and temperature

  Open serial monitor at 9600 baud to see readings. Errors 998 if not sensor is detected. Error 999 if CRC is bad.
