Humidity Controllers
Humidity controllers, also known as humidistats or hygrostats, are devices used to measure and control the humidity level in an environment. They are commonly used in residential, commercial, and industrial settings to maintain optimal humidity levels for comfort, health, and process control. Here are some key points about humidity controllers:
Measurement of Humidity: Humidity controllers incorporate sensors that measure the relative humidity (RH) in the air. The most common sensor used is a capacitive sensor, which detects changes in electrical capacitance caused by moisture absorption.
Control of Humidity: Once the humidity is measured, the humidity controller compares it to a pre-set desired humidity level. Based on this comparison, the controller activates or deactivates a humidifier or dehumidifier to adjust the humidity level accordingly.
