SKU: rz24313530 Category: Gas and Dust Sensor

Description

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 electro circuit, Convert change of conductivity to correspond output signal of gas concentration.

Applications:

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

Feature:

Lower consumption
Small size
Fast response and resume
Highest sensitivity
Excellent stability and long life
Easy circuit and big signal output
Excellent selectivity
