These Humidity Sensors can be used to detect the environmental relative humidity. Used in many end products such as air conditioners, humidifiers, dehumidifiers, hygrometers, recorders, and transmitters. A humidity Sensor is an instrument used for measuring the moisture content in the environmental air or powders. Most measurement devices usually rely on measurements of some other quantity such as temperature, pressure, mass, or a mechanical or electrical change in a substance as moisture is absorbed.

From calculations based on physical principles, or especially by calibration with a reference standard, these measured quantities can lead to a measurement of humidity. Modern electronic devices use temperature of condensation, or changes in electrical capacitance or resistance to measure humidity changes.
