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 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.

This sensor comes in a package similar to our MQ-3 alcohol sensor, and can be used with the breakout board below.

• Power supply: 5 Vdc or AC
• Operating temperature: from -10 ° C to + 50 ° C
• Heating consumption: less than 950 mW
• Dimensions (mm): diameter 19.6x14.5
• LPG: 300 ppm - 10,000 ppm
