LPG Sensor with MQ-6 and Arduino | Microcontroller Tutorials

MQ-6 Gas Leak Detector. If you want to detect only the presence of LPG in the air, you only need to connect the AO pin to any analog pin of the Arduino UNO. Then you must determine the threshold value by placing the MQ-6 near a safe LPG source (like an unignited gas stove) and record the reading. Note that the MQ-6 needs at least 20 seconds to ...
