Alcohol gas gas sensor MP-3B

semiconductorfor air quality monitoringfor automotive

MP-3B 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 (alcohol) 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. Application It is used for detecting whether the driver and other people who drink alcohol, or detecting whether ethanol steamy exist in other places. Features Lower consumption Small size Fast response and resume Highest sensitivity Excellent stability and long life Easy circuit and big signal output Excellent selectivity
