MQ-9 Carbon monoxide, Methane and LPG gas detection sensor module

MQ-9 Carbon monoxide, Methane, and LPG gas detection sensor module

This is MQ-9 Carbon Monoxide, Methane, and LPG Gas Sensor Module can be used to sense Carbon Monoxide and Methane Gas. The sensitive material of the MQ9 gas sensor is SnO2, which has lower conductivity in clean air. It makes detection by the method of the cycle of high and low temp. It detects CO when the temp. is low. The sensor’s conductivity is higher along the gas concentration is high.

Advantages:-

1. Good sensitivity to CO/Combustible Gas
2. High sensitivity to Methane, Propane, and CO
3. Long life and low cost
4. Simple drive circuit
5. The domestic gas leakage detector
6. Industrial gas detector
7. Portable gas detector
