Product Introduction
I.Propane Gas Sensor(C3H8 Gas Sensor) MP-5 Product Description
The MP-5 planar semiconductor gas sensing element for combustible gas detection uses advanced planar production technology, forming a heater and metal oxide semiconductor gas sensing material on a miniature Al2O3 ceramic substrate, with electrode leads extracted and packaged in a metal base and cap. When the detected gas is present, the higher the concentration of the gas in the air, the higher the conductivity of the sensor. A simple circuit can convert this change in conductivity into an output signal corresponding to the gas concentration.
