As a converter to convert volume fraction of a certain gas into corresponding electrical signal, the Semiconductor Gas Sensors are mainly applied for civil use. It is for that these sensors are relatively cheap while their performance can meet the requirements of home alarms.
To be specific, gas sensors are used in following applications: in kitchens, sensors detect leakage of natural gas, liquefied petroleum gas and city gas. They also measure gas generated by microwave ovens and control them while cooking. Sensors detecting CO2, smoke and O3 are used to control the automatic operation of air purifiers or fans. In some high-rise buildings, gas sensors are used to detect fires and make alarms.
At present, with the development of gas sensitive materials, gas sensors are featuring with high sensitivity, stable performance, simple structure and compact size. Their price are low but their selectivity and sensitivity are enhanced.
