Humidity Sensors

Essential devices for measuring humidity levels in the air, humidity sensors guarantee a level of accurate monitoring necessary for a host of industrial, environmental, and domestic applications. These sensors function by detecting water vapor in the air—more precisely, they yield readings of relative humidity, which denotes the ratio of the amount of moisture in the air compared to the maximum amount it could hold at a given temperature. Among the most commonly used types of humidity sensors are humidity-capacitive sensors, which work in virtue of the electric properties of their internal elements. Changes in capacitance levels—that is, the ability of a material to store an electric charge—resulting from different moisture levels in the air yield high-fidelity digital outputs.

Humidity sensors offer an accurate measurement of both types of humidity, which are absolutely necessary for ensuring the energy efficiency and overall optimization of a wide array of industrial processes. Take, for instance, their use in HVAC systems. Here, humidity sensors serve a crucial role both in ensuring the total system functions as intended (i.e., uses the least amount of energy possible while maintaining the proper comfort conditions of temperature and humidity for the building occupants) and in providing a level of comfort.
