QM1H0P0073 Sensors, Transducers

Humidity and moisture sensors are an important part of numerous building automation systems, allowing for the monitoring of environmental, temperature, and humidity conditions. The QM1H0P0073 is one such device that has a wide range of application fields. This article will discuss its various applications and its working principle.

Application Fields

The QM1H0P0073 is capable of detecting both humidity and temperature in a wide range of indoor and outdoor environments. It is particularly suitable for controlling and monitoring water damages, providing dry contact alarms for roof drainage systems. In addition, the device can be used in cooling equipment, air conditioners, and domestic appliances, allowing for optimized energy efficiency.

The device is also suitable for outdoor industrial applications such as electronic recorders, energy management systems, and office automation. It can also be used in order to detect water damage for industrial plants, boilers, and fire fighting systems. Finally, the device is also able to detect the moisture of various grains and other materials in factory warehouses and silos.

Working Principle

The QM1H0P0073 employs a galvanic exchange principle in order to measure humidity and temperature. The device utilizes a replaceable humidity sensing element to detect the presence of water droplets on its surface. The element contains two plates; one is a water-absorbing material and the other is an insulator. When water comes into contact with the humidity sensing element, a small electric current is generated, which is then detected by the Condenser Sensor Unit of the device. The device then converts the detected current into a humidity reading.

The device is also able to measure temperature using a surface-mounted thermistor, which is essentially a semiconductor device that changes its resistance depending on its temperature. The thermistor detects the temperature of its surroundings, and the device amplifies the detected temperature and converts it into a digital reading which is then passed onto the display unit.

Conclusion

The QM1H0P0073 is a useful device for monitoring air humidity and temperature conditions. It is versatile enough to be used in a variety of different indoor and outdoor environments, and is suitable for industrial, commercial, and domestic application. The device utilizes a galvanic exchange principle and a surface-mounted thermistor in order to provide precise and accurate readings of both temperature and humidity.
