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.
