A Stevenson Screen for the Adafruit HTU21D temperature and humidity sensor. Check out the full tutorial http://steelcityelectronics.com/electronics/neopixel-htu21d-weather-station/ 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. Full construction details are available at http://steelcityelectronics.com/electronics/neopixel-htu21d-weather-station/ All components were printed with 30% infill and thick shells. These settings resulted in a strong and durable print. Supports are necessary. The lid sits in position with a locking mechanism. A 123D model is provided so the base can be modified to suit the diameter of your mounting post. Use two 3mm screws to secure the sensor to the standoff. The hole spacing suits an Adafruit HTU21D temperature and humidity breakout board.
