Piezoresistive sensors

Piezoresistive humidity sensors are advanced devices used to measure relative humidity levels in various environments. They are designed to detect changes in the electrical resistance of a moisture-sensitive material based on ambient humidity, providing accurate and reliable humidity measurement.

Advanced Operation:

Piezoresistive humidity sensors exploit the property of piezoresistive materials, which change electrical resistance in response to mechanical deformation, such as that caused by moisture absorption. When moisture-sensitive material absorbs water, it expands, causing deformation that results in a change in electrical resistance. This change in resistance is then measured and converted into an accurate relative humidity reading.
