Check out the full tutorial
This housing keeps your sensor shaded and protected from wind gusts - allowing the ambient conditions to be sampled by your sensor.
A standoff is included to secure your sensor in the centre of the housing - suits the dimensions of the Adafruit HTU21D breakout. Use two 3mm screws to secure the sensor to the housing.
