MP-5 Sensor de gas propano Gas combustible licuado 300-10000ppm Módulo de sensor de sonda de alarma MP5

Product Details:

MP-5 combustible gas detection with planar semiconductor gas sensor using advanced planar production process, in the micro-Al2O3 ceramic substrate on the formation of heaters and metal oxide semiconductor gas-sensing material, with the electrode lead leads, packaged in the metal tube, tube Cap inside When there is a gas to be detected, the higher the concentration of the gas in the air, the higher the conductivity of the sensor. The conversion of this conductivity can be converted to an output signal corresponding to the gas concentration using a simple circuit.

Application:

For the home environment of harmful gas detection automatic exhaust device, air refresher and so on.
