This solar radiation sensor or pyranometer is an instrument for measuring solar radiation. It measures the solar energy received from the entire hemisphere (180 degree field of view). Solar radiation varies significantly among regions. Season and time of day are major considerations, but surrounding terrain elevation, man-made obstructions, and surrounding trees can also cause large variations in locations with a small area.

The RS-RA--AL-EX solar radiation sensor uses the photoelectric principle to measure the total radiation value under sunlight.The radiation sensor uses high-precision photosensitive elements, wide spectrum absorption, high absorption in the full spectrum range, and good stability.

We install a dust cover with a light transmittance of up to 95% outside the sensing element. This cover undergoes special treatment to reduce dust adsorption, effectively preventing environmental factors from interfering with internal components. As a result, it can more accurately measure solar radiation
