What Is The Solar Radiation Sensor For?
A solar radiation sensor measures solar energy from the sun.
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.
The units of measure are Watts per square meter.
The device is typically used in agricultural applications, and is used in the calculation of Evapotransportation.
Evapotransportation is the potential for evaporation of moisture from the soil (or the reverse of rainfall) and is a function solar energy, wind and temperature.
The Pyranometer is the main light sensor on an automatic weather stations, as it indicates the amount of total sunshine. It is also used by Solar Panel installers to check outputs from the solar panels.
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.
solar radiation sensor adopts photoelectric principle and can be used 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. A dust cover with a light transmittance of up to 95% is installed outside the sensing element, and the dust cover is specially treated to reduce dust Adsorption can effectively prevent environmental factors from interfering with internal components, and can more accurately measure solar radiation.
The spectral response of the pyranometer is not as wide as a Thermopile - however it covers all visible light and into the Infrared and Ultra Violet spectrums. This captures 90% of the incoming solar radiation energy in natural daylight. The calibration ensures the accuracy is suitable for use in most applications.
