Outdoor Aspirated Shield

Outdoor temperature and humidity affect many systems within a house and are critical measurements for a variety of reasons. Outdoor temperature and humidity are most often measured with a combined temperature and relative humidity sensor that is housed in an aspirated shield so that it does not artificially heat up in the sunlight. Outdoor aspirated shields have a different geometry than an indoor aspirated shield for temperature measurements, but have the same purpose. An aspirated shield for outdoor temperature and humidity measurement is shown below with an anemometer.

Photo shows an aspirated shield for outdoor temperature and humidity measurement with an anemometer. This aspirated shield for outdoor temperature and humidity measurements is made of white plastic shield layers. A cylindrical hole extends up through the bottom four shield layers so that the top of the sensor will sit just below the fifth shield layer.
