Solar Radiation Sensor

SAE-WS-400-A1 Solar Radiation Sensor is designed on basis of silicon-cell principle. It is mainly used for measuring solar radiation within 300-3000nm wavelength. If the sensing face is downwards, it can test the reflected radiation and solar radiation on the incident to the inclined plane. If shad is added, it can test the scattered radiation. It is widely used to monitor the solar radiation in meteorology, solar energy, agriculture, construction materials aging and atmospheric pollution and etc..

  • The product can be used as a sunshine time sensor

Sunshine hours is the sum of time periods that the sun direct irradiance intensity to reach or exceed 120W/m2 time , hour as a unit, a decimal. Sunshine hours is also known as actual irradiance time.
