Pyranometer

A pyranometer is a device that measures the amount of energy that comes from the sun. It is a special tool that helps us understand how much sunlight is being sent to Earth.
Think of it like a thermometer, but instead of measuring temperature, it measures how much sun is shining on a particular spot. It has a special sensor on top that absorbs sunlight, and then it measures how much energy or heat is in that sunlight. This tool is important because sunlight is what makes plants grow and helps us make electricity from solar panels, so we need to know how much of it we are getting. Scientists and researchers use pyranometers to keep track of how much sunlight is reaching different parts of Earth.
