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 electrocircuit, convert change of conductivity to correspond output signal of gas concentration.
Features:
* Good sensitivity to LPG, smoke in wide range
* Small size
* Long lifespan
* Low cost
*Simple circuit
Application Domestic smoke leakage alarm, industrial smoke gas alarm and portable smoke detector
