"Robust and reliable solution for measuring solar irradiation"
What is Solar Irradiance Sensor?
The Irradiance sensor also referred to as a photovoltaic pyranometer, has emerged as a derivative of pyranometers with the development of photovoltaic systems. Its purpose is to measure the irradiance value from the sun. What sets irradiance sensors apart is their cost-effectiveness and low maintenance requirements.
Solar radiation on Earth is commonly characterized as the overall radiation encompassing wavelengths from 280 to 4000 nm, which is known as shortwave radiation. The total solar radiation, whether it’s in the form of a direct beam or diffuse radiation, received on a horizontal surface is referred to as global shortwave radiation or shortwave irradiance, and it is measured in watts per square meter.

Specifications & Features
The Irradiance sensor operates based on the Thermoelectric Effect, where sunlight absorbed by the sensor is converted into heat. This heat then transfers through the sensor to the housing of the device. By utilizing the principle that the short circuit current is directly proportional to the radiation received, the Irradiance sensor effectively measures the radiation and presents it in the form of voltage or current.
To serve as an Irradiance sensor, a monocrystalline solar cell is employed in our sensors. This solar cell is connected to a shunt, which functions alongside the low circuit. The measurement signal from the cell’s short circuit current, as well as the resistance of the temperature sensor, is processed by a microcontroller.
