Product Description: MQ9 Gas Sensor Module
The sensitive material of the MQ-9 gas sensor is SnO2, which with lower conductivity in clean air. It makes detection by method of cycle 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 the high temperature (heated by 5.0V), it detects Methane, Propane, etc combustible gas and cleans the other gases adsorbed under low temperature. Please use a simple electro circuit, Convert the change of conductivity to correspond output signal of gas concentration.MQ-9 gas sensor has high sensitivity to Carbon Monoxide, Methane, and LPG. The sensor could be used to detect different gases containing CO and combustible gases, it is low cost and suitable for different applications.
The gas Sensor (MQ9) module is useful for gas leakage detection (in home and industry). It is suitable for detecting LPG, CO, and CH4. It provides an analog output corresponding to the concentration of the gases in the air and an easy-to-use digital output. The onboard potentiometer can be used to set the maximum gas concentration beyond which the digital output gets triggered. Just power the module with 5V set the threshold and you can start getting the gas concentration of the air around the sensor! An onboard LED signals the presence of any gas. The digital output can be easily interfaced with microcontrollers and other circuits. The analog output can be hooked up to an ADC of a microcontroller to get a wide range of sensor readings.
