| Additional Information | Suitable for home or factory gas leakage monitoring devices. |
| Package Include | 1 x MQ-9 Carbon monoxide 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. When temperature rises (heated by 5.0V), it detects Methane, Propane, combustible gas, etc and cleans the other gases as it adsorbed under low temperature. MQ-9 usually Applied in domestic gas leakage detector, industrial gas detector, portable gas detector, etc.
