This LPG gas sensor (MQ6), ideal sensor to detect the presence of a dangerous leak of LPG in your home, car or service station, in the storage tank environment. This unit can be easily incorporated into an alarm unit, to sound an alarm or give a visual indication of the Gas / LPG concentration. The sensor has excellent sensitivity combined with fast repsonse time. The sensor can also detect iso-butane, propane, LNG and cigarette smoke. This LPG Gas Sensor can be used to make Wireless Gas Leak Detector in the home security system.
The circuit for a LPG leak detector is readily available on the market, but is extremely expensive and generally based on a microcontroller (MCU). Here is presented a low cost circuit for a GLP detector that can be easily built. The main purpose of the circuit is to detect LPG leaks anywhere. Figure 1 shows the prototype of the author.
