The mV Perc Irradiance Sensors manufactured by VSIAS under the brand name Visionsen are specifically designed for high-accuracy solar radiation measurements at lower costs than thermopile pyranometers for outdoor monitoring of solar power plants. The mV Perc Irradiance Sensor is a measuring device used to measure the intensity and wavelength of sunlight. The irradiance sensor uses photovoltaic (PV) cells to determine solar radiation. The irradiance sensors measure the response of photovoltaic cells to sunlight and calculate the amount and intensity of sunlight based on this response. The mV Perc Irradiance Sensors are widely used in many industrial applications such as solar power plants, agriculture and greenhouse farming etc.
