Hygrometer

A hygrometer is a device that measures the humidity, or moisture level, in the air. It helps determine how much water vapor is present in the environment, which can affect comfort, health, and various processes like weather forecasting or maintaining ideal conditions for stored items. There are different types of hygrometers, such as digital ones that use electronic sensors and traditional analog models that rely on materials changing shape or appearance with humidity. By providing accurate humidity readings, hygrometers assist in indoor climate control, ensuring optimal conditions for people, plants, or equipment.
