When there is a fire a lot of gas particles are produced. The sensor detects these and turns the electricity supply on. It can be used to detect the presence of carbon monoxide gas (CO). Smoke alarms or gas alarms work on the same principle.
MP-2 model with advanced planar construction is comprised of heater and metal oxide
semiconductor material of subminiature Al2O3 ceramic plate, fetch out electrode down-lead,
encapsulation in metal base and cap. When the target gas exists , the sensor’s conductivity is
more higher along with the gas concentration rising. Please use simple electro circuit, convert
change of conductivity to correspond output signal of gas concentration.
