Humidity sensors are the most commonly used environmental sensor. It is one of the essential measures to get right when one is looking to create a comfortable, safe and energy-efficient environment. What are Humidity Sensors? Humidity is a term that refers to the presence of water vapours in the environment. It affects not only personal comfort but also affects various manufacturing processes. Humidity sensors are the electronic device that measures the humidity in the environment and converts its findings into an electrical signal. These sensors are often referred to as hygrometers. Humidity control is vital for incubators, sterilizers and biological products. A humidity sensor measures and report both moisture and environment temperature. On the basis of humidity measured by the sensor, these are classified as:
- Relative Humidity Sensor.
- Absolute Humidity Sensor.
How does the Humidity Sensors work? The humidity sensor consists of a polymer that reacts with the water vapour in the air and two electrodes on each side of the polymer. As the humidity in the environment changes, the polymer will absorb and release the water vapour. When the water vapour is released, it changes the electrical capacitance of the sensor. Importance of Humidity Sensors
- Measuring humidity can be critical. Humidity measurement in Industries is essential owing to the fact that it can affect the health and safety of personnel as well as the cost of the products.
- Humidity measurement is also crucial for weather reports. The presence of humidity in the environment shows the chances of dew, fog or precipitation. Higher relative humidity reduces the effectiveness of sweating; therefore, it may feel hotter during summers in areas where there is higher relative humidity as compared to the place where humidity is not high.
While choosing a humidity sensor, the following specifications should be considered:
- Accuracy
- Linearity
- Reliability
- Long-term stability
- Resistance to physical and chemical contaminants
- Cost-effectiveness
- Packaging
Application of Humidity Sensors
These sensors are employed by people who are affected by humidity. The application of humidity sensors is far more comprehensive. These are used in offices, cars, museums, industrial space and meteorology stations to report and predict the weather. It is also found as a part of home heating, ventilating and air conditioning systems.
