MQ-9 Carbon Monoxide, Methane and LPG Gas Sensor Module

RWF 7,500.00

It makes detection by the method of cycle high and low temperature, and detect CO when the low temperature (heated by 1.5V). The sensor’s conductivity is higher along with the gas concentration rising.


MQ-9 Carbon Monoxide, Methane, and LPG Gas Sensor Module can be used to sense Carbon Monoxide and Methane Gas. Sensitive material of the MQ9 gas sensor is SnO2, which with lower conductivity in clean air.


  • Good sensitivity to CO/Combustible Gas
  • High sensitivity to Methane, Propane, and CO
  • Long life and low cost
  • Simple drive circuit
  • Input voltage: DC 5±0.2V
  • Current Consumption: 150mA
