Humidity sensors are sensors that convert the
moisture content in air, gases, bulk materials or soil into an electric output
signal. It is a humidity sensor device which is also known as hygrometer
measures and regularly updates the relative humidity in air. It measures both
air temperature and air moisture. Humidity sensor is composed of two metal
plates with a non-conductive polymer film between them. The film collects
moisture from the air which causes minute changes in the voltage between the
two plates. Humidity sensors are generally used in textile machines,
woodworking machines, printing and paper machines for measuring humidity in
air.
Some of the major advantages of humidity sensors
over conventional sensors low power requirement, easy implementation and
betterment of transducer performance such as sensing elements, structure
design, principle of mechanism, and fabrication technologies. Major
disadvantages of humidity sensor market are high cost, frequent mirror
contamination and insatiability under continuous use.
Miniaturization
of electronic device is one of the major trend in the global humidity sensor
market. Technology advancement and increasing demand in devices with
high end feature are driving the market for humidity sensor. On the other hand
continuous reduction in prices of sensors due to the introduction of more
competitive technologies and higher associated costs are restraining the market
growth. The humidity sensor market is segmented on the basis of unit of
measurement, by product type, by application and by geography.
On the basis of
type the market is segmented into Relative humidity sensor and Absolute
humidity sensor. Further, relative humidity sensor is further sub-segmented
into ceramic, semiconductor and organic polymer processing and absolute
humidity sensor are sub-segmented into solid moisture and mirror based sensor.
On the basis of type humidity sensor is segmented into Thermoset sensor,
thermoplastic sensor, bulk thermoplastic sensor, lithium chloride sensor and
thermoset polymer capacitor sensor. Further on the basis of application the
market is segmented into food industry, mining industry, cement industry and
pharmaceutical industry. On the basis of geography the market is segmented into
North America, Latin America, Western Europe, Eastern Europe, Asia-Pacific, Japan
and Middle East & Africa
