Adafruit Si7021 User Manual

We put this nice sensor on a breakout board with a 3.3V regulator and level shifting so you can use it safely with 3.3V
or 5V power & logic. There's a PTFE filter to keep the sensor clean, that's the white flat thing on top. Also comes with
some pin header. Some light soldering is required to attach the header but it's easy to do.
