What is a Pyranometer and How is it Used to Measure Solar Radiation?

A pyranometer is a specialized instrument designed to measure solar radiation flux density. It plays a crucial role in meteorology, climatology, solar energy studies, and agriculture by providing accurate data on sunlight intensity.

How a Pyranometer Works

These devices utilize a thermopile sensor that generates a voltage proportional to the solar radiation absorbed. This data helps in assessing available solar energy and environmental conditions.

Key Applications and Benefits

From optimizing solar panel efficiency to agricultural planning, pyranometer is used to measure critical parameters that influence renewable energy systems and ecosystem studies.
