A silicon microchip, housed in a plastic shell, sends an electrical charge to a small detection chamber that contains a CO sensor. This sensor can detect and measure CO concentration in the atmosphere. If the sensor detects high levels of CO, the microchip will trigger an alarm

Sensitive material of MQ-7B gas sensor is SnO2, which with lower conductivity in clean air. It make detection by method of cycle high and low temperature, and detect CO at low temperature(heated by 1.5V).The sensor’s conductivity gets higher along with the CO gas concentration rising. At high temperature (heated by 5.0V),it cleans the other gases adsorbed at low
temperature. Users can convert the change of conductivity to correspond output signal of gas concentration through a simple circuit.

Applications: 

It is widely used in domestic CO gas leakage alarm, industrial CO gas alarm and portable CO gas detector.
