How do humidity sensors work?

A humidity sensor (or hygrometer) senses, measures and reports both moisture and air temperature. ... Humidity sensors work by detecting changes that alter electrical currents or temperature in the air. ... As humidity changes, so does the resistance of the electrodes on either side of the salt medium. read more

Humidity sensors work by detecting changes that alter electrical currents or temperature in the air, according to Sensors Online. There are three basic types of humidity sensors: capacitive, resistive and thermal. read more

Humidity sensors detect the relative humidity of the immediate environments in which they are placed. They measure both the moisture and temperature in the air and express relative humidity as a percentage of the ratio of moisture in the air to the maximum amount that can be held in the air at the current temperature. read more

A humidity sensor is a device that measures the relative humidity of in a given area. A humidity sensor can be used in both indoors and outdoors. Humidity sensors are available in both analog and digital forms. read more
