Ambient Temperature & Relative Humidity Sensor

The Temperature/Humidity Sensors includes temperature and humidity sensors and a passive solar radiation shield or a 24- Hour Fan-Aspirated Radiation Shield. The Temperature/ Humidity Sensor measures relative humidity and air temperature. The passive solar radiation shield is made of a Proprietary plastic designed for high thermal reflectance and low thermal conductivity. The 24-Hour Radiation Shield includes a solar-and battery-powered fan that pulls air up through the shield and over the sensors for highest Temperature accuracy. .
