The MQ - 6 is an easy - to - use liquefied petroleum gas (LPG) sensor. Ideal for detecting LPG, which is mainly made up of propane and butane, in the air. It can accurately sense gas concentrations ranging from 200 to 10000ppm. This sensor stands out with its high sensitivity and rapid response time. Its output is an analog resistance. The drive circuit is straightforward: just power the heater coil with 5V, add a load resistance, and connect the output to an ADC. It comes in a package similar to our MQ - 3 alcohol sensor and can be paired with the breakout board below. Included documents are the datasheet and a wiring example.
Using the MQ - 6 LPG gas sensor is easy. First, make sure to power the heater coil with 5V. Then, add a load resistance as described. Connect the output to an ADC. This will let you start detecting LPG concentrations in the air. When using, keep it away from strong electromagnetic fields as they might interfere with its readings. For maintenance, keep it clean and free from dust. Check the connections regularly to ensure they are secure. If you want more detailed information, refer to the included datasheet and wiring example.
