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.
Note: For more technical details go through Datasheet in the attachment section
