Capacitive humidity sensors are devices designed to measure the moisture content in the air. They operate on the principle of detecting changes in capacitance when exposed to varying levels of humidity.
These sensors comprise two conductive plates separated by a dielectric material. When humidity changes, the dielectric material's permittivity also changes, altering the sensor's capacitance.
Capacitive humidity sensors play a vital role in various applications by accurately detecting changes in moisture content. Their high accuracy, wide range, and cost-effectiveness make them an ideal choice for monitoring air quality, preventing water damage, and controlling industrial processes.
