Pyranometer

A pyranometer is a scientific instrument used to measure solar radiation received on a surface, typically expressed in watts per square meter (W/m²). It is specifically designed to measure the solar irradiance from the sun, taking into account both direct sunlight and diffuse sky radiation. Pyranometers consist of a sensor that detects radiation, often using a thermopile or a photodiode, and a transparent dome or glass cover that allows solar energy to enter while protecting the sensor.
