MP135 Air Pollution Gas Sensor DIP-4
Air pollution plane of the semiconductor gas sensor MP135
Air pollution plane of the semiconductor gas sensor MP135 use of advanced production technology plane, in miniature Al2O3 Heater and metal oxide semiconductor gas material is formed on the ceramic substrate, with the electrode wire leads, packaged in a metal tube socket, pipe cap. When there When detecting the presence of gas, the gas concentration in the air is higher, the higher the conductivity sensor. Using a simple circuit can be converted to this change in conductivity and an output signal corresponding to the gas concentration.
