Duct Mounted Humidity Sensor

A duct mounted humidity sensor is a device that is designed to measure the humidity levels in an air duct system. It is typically mounted directly onto the duct and is used to detect the relative humidity of the air passing through the duct. The sensor is typically composed of a sensing element, a housing, and a wiring system. The sensing element is usually a thermistor, a thermocouple, or a capacitive humidity sensor. The housing is designed to protect the sensing element from environmental conditions, while the wiring system connects the sensor to the control system. The sensor measures the relative humidity of the air passing through the duct and sends the data to the control system. This data is then used to control the humidity levels in the duct system. The duct mounted humidity sensor is an important component of any air duct system, as it helps to ensure that the air quality is maintained at a comfortable level.
