Fire gas sensor is booming

Sensor technology in the fire , the fire gas sensor technology started late, but rapid development , especially in the field of early fire alarm fires become more and more attention of researchers and has developed various types of fire, gas sensors and smart , composite gas fire sensors. Currently, the fire continues to move gas sensor miniaturization , intelligent and multi-parameter , multi- criteria composite probing direction.With Cooling Temperature Sensor technology and application of new materials and the development of microelectronics technology , fire, gas sensors becoming smaller , miniaturization . Resistance using nanoparticles composed of gas with the surrounding environment changes and changes in the characteristics of nanomaterials can be made ​​gas sensors, toxic gases, flammable gas detection and quantitative measurement . Because nanomaterials crystal surface catalytic activity, as well as having a porous structure and other characteristics , the use of nano- crystalline film produced gas sensor has more choice and anti-interference, improving the accuracy of the fire alarm to reduce falsepositives.Meanwhile,thesmallsizeofnanomaterials,surface area is small , greatly reducing temperature , reducing power consumption, so that the fire gradually sophisticated gas Car Temperature Sensorminiaturization .Yin Nami , film and other new materials preparation technology successfully applied to the fire gas sensors and intelligent integration provides a good prerequisite. Fire gas sensor will make full use of micromechanical and microelectronic technology, computer technology , signal processing technology, circuits and systems , sensor technology, bionics , neural networks, fuzzy theory and other subjects on the basis of integrated technology to develop. Able to simultaneously monitor multiple gas developed automatic intelligent digital gas sensor , will be the next major development in this field .Fire is an extremely complex physical and chemical processes in different environments and different resultant fires burning material , such as gas composition , smoke particle size , temperature distribution and spectral composition are different , only one fire detection parameters vagaries the various types of fire is bound to have great difficulty , it may cause a false positive signal non-fire dust , water, gas , smoke, etc. do not have the real fire parameters . Therefore, multi-parameter , multi- composite fire detection criterion can not only overcome the single fire caused by false positives parameter , you can also identify the non-fire signaling leads to false positives , the future is still hot fire gas Engine Water Temperature Sensor . In addition, multi-parameter , multi- criterion composite gas fire detection sensor also allows to reduce the time to achieve early warning .
