Gas Sensor MQ-5 Sensitive Natural Gas LPG Goal

MQ5 is a semiconductor sensor which can detect the presence of LPG, Natural and Coal gases at concentrations from 200 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. It has also some sensitivity to smoke and alcohol. MQ5 LPG natural gas sensor module can be easily interfaced with Microcontrollers, Arduino Boards, Raspberry Pi etc.
