MQ-7 Carbon monoxide gas detection sensor module

The sensitive material of the MQ-7 gas detection sensor is SnO2, which has lower conductivity in clean air. It makes detection by using the method of the cycle of high and low temperature. It detects CO at when the low temperature. The sensor’s conductivity is higher along with the gas concentration rising. At high temperatures, it cleans the other gases.


  1. High sensitivity to Natural gas
  2. Long life and low cost
  3. Simple drive circuit
  4. Domestic gas leakage
  5. Industrial CO detector
  6. Portable gas detector
