Solar radiation is radiant energy emitted by the sun from a nuclear fusion reaction that creates electromagnetic energy. The spectrum of solar radiation is close to that of a black body with a temperature of about 5800 K. About half of the radiation is in the visible short-wave part of the electromagnetic spectrum. The other half is mostly in the near-infrared part, with some in the ultraviolet part of the spectrum.

Solar radiation sensor is designed on basis of silicon-cell principle. It is mainly used for measuring solar radiation within 300-1100nm wavelength. If the sensing face is downwards, it can test the reflected radiation and solar radiation on the incident to the inclined plane. PAR sensor is mainly used for measuring solar radiation within 400-700nm wavelength. It is easy installation and can work continuously in all weathers. When there is sunlight, voltage output proportional to incident light intensity will be generated by the silicon-photo detector in the sensor. 

Radiation sensor works by measuring the number of small units of light, known as photons that impact a physical or chemical device located within the instrument. Solar radiation sensors are typically not powered due to the fact that the components located in the device either are influenced by or react to solar radiation in a direct manner.

When buying radiation sensors, it's essential to select the right device that accurately detects and measures various types of radiation, whether ionizing or non-ionizing. These sensors play a pivotal role in safeguarding human health, protecting the environment, and advancing scientific research.
