LPG Gas Sensor – MQ-6 with Breakout Board

This is a simple-to-use liquefied petroleum gas (LPG) sensor, suitable for sensing LPG (composed of mostly propane and butane) concentrations in the air. The LPG Gas Sensor MQ-6 can detect gas concentrations anywhere from 200 to 10000ppm

This sensor has a high sensitivity and fast response time. The sensor’s output is an analog resistance. The drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC.
