Carbon monoxide sensor
 

  Product Information
  • • Detection Gas: CO, carbon monoxide
  • • Detection Range: 10~500ppm CO
  • • Application: It is widely used in domestic CO gas leakage alarm, industrial CO gas alarm and portable CO gas detector.
Principle Introduction:

Original manufacturer of MQ-7B Carbon Monoxide gas sensor, CO Gas sensor, with 80% market share in gas sensor field.
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.
Technical parameters :

Tips:For more parameter information, please refer to the latest manual provided by salesman.
