This sensor module is made using MQ9, a low cost semiconductor sensor which can detect the presence of carbon monoxide gas at concentrations from 10 to 1000 ppm and combustible gases at concentrations from 100 to 10,000 ppm. The sensitive material used for this sensor is SnO2, whose conductivity is lower in clean air. It’s conductivity increases as the concentration of sensing gases increases. This module provides both digital and analog outputs. MQ9 CO Combustible gas sensor module can be easily interfaced with Microcontrollers, Arduino Boards, Raspberry Pi etc using an Analog to Digital Converter (ADC).
