low power consmption alcohol sensor with fast response

1.Lower voltage and consumption 2.mini size 3.stable performance 4.high sensitivity 5.RoHS

Flat Surfaced GAS SENSOR

 

MP-3 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) exist , 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:

Full solid state semiconductor alcohol sensor

 Lower voltage and consumption

 Small size

 Fast response and resume

 Highest sensitivity

Excellent stability and long life

 Easy circuit and big signal output

Excellent selectivity 

 

Application

It is used for detecting whether the driver and other people who drink alcohol, or detecting whether ethanol steamy exist in other places.
