hygrometer
Air moisture meter
A hygrometer is an instrument for measuring humidity—the amount of moisture in the air.
Various designs exist, from simple hair-tension devices to electronic sensors.
Hygrometers appear in weather stations, greenhouses, museums, and HVAC systems where controlling moisture levels matters.
