Scattered radiation sensor

Scattered radiation sensor measures the value obtained from the shielding of the direct part of the sun as the scattered radiation, which is the short-wave radiation.The Scattered radiation sensor consists of a pyranometer and a sunshade ring. The sunshade ring is used to block direct solar radiation from sunrise to sunset. The sunshade ring consists of a sunshade ring, a ruler, a screw adjustment screw, a bracket, and a chassis. The sunshade ring is 65mm wide and 400mm in diameter. It is fixed on the screw adjustment screw of the ruler, which is engraved with latitude and declination scales. The ruler and the bracket are fixed on the chassis and should be fixed according to the geographical latitude of the mounting location.
