Humidity Sensor

Humidity is defined as the amount of water vapor in an atmosphere of air or other gases. The most commonly used term to measure humidity is “Relative Humidity (RH)”. RH is a ratio of actual amount of water vapor (content) in the air compared to the maximum water vapor the air is able to hold (capacity) at that temperature.

Through measuring humidity, you can ensure that processes run smoothly, and that actions can be taken immediately when there is any sudden change. Applications include industrial and office environments for heating, ventilating, and air conditioning systems control. Humidity sensors are often combined with temperature sensors for condition monitoring.

Humidity sensors typically cover a humidity measurement range of 0 to 100 % RH with an accuracy of ±3 % RH.

Use Cases for Condition Monitoring using Humidity Sensors

Sensing humidity can be a beneficial addition to indoor positioning systems. Here are some examples:

With knowledge of the air humidity, measures can be taken against the formation of condensation and thus against a possible health-endangering mold infestation in living and working rooms.

Relative humidity is an essential element of collections care. Mold, pests, deterioration and warping can occur if humidity and temperature are not stable and controlled. A humidity sensor helps to support the preservation of exhibits in archives, historic buildings and museums.
