MQ9 Gas Sensor Module


MQ-9 gas sensor module has high sensitivity to Carbon Monoxide, Methane and LPG. Sensitive material of MQ-9 gas sensor is SnO2, which with lower conductivity in clean air. It makes detection by cycling high and low temperature, and detects CO when low temperature (heated by 1.5V). The sensor’s conductivity is higher along with the gas concentration rising


Specification of MQ9 Carbon Monoxide, Methane and LPG Gas Sensor Module:-
Input voltage: DC 5V
Power: 150mA
DO output: TTL digital 0 and 1 (0.1 and 5V)
AO output: 0.1-0.3V (relatively clean), the highest concentration voltage is about 4V.
