High-low temperature cycling detection mode (1.5V heating) carbon monoxide detector, conductivity sensor with the increasing concentration of carbon monoxide gas in the air increases,high-temperature (5.0V heating) cleaning cryoadsorption stray gases. Using a simple circuit to change the conductivity, concentration of the gas is converted to the corresponding output signal.
