Humidity sensors are devices used to detect and measure the amount of water vapor present in air or other environments. They commonly measure relative humidity, which expresses the moisture in air as a percentage of the maximum amount the air can hold at a given temperature. Humidity sensors may use technologies such as capacitive, resistive, or thermal sensing to convert changes in moisture into an electrical signal. They are widely used in weather monitoring, HVAC systems, industrial equipment, agriculture, healthcare devices, consumer electronics, and environmental monitoring. Modern humidity sensors can be integrated with temperature sensors and digital electronics, allowing continuous monitoring and automated control of humidity-sensitive environments.
