RhydoLabz s LPG Gas Sensor Module is designed to detect the presence of a dangerous LPG leak in your Home, car or in a service station, storage tank environment by interfacing with Microcontroller without ADC Channels and programming. In this version of LPG Gas sensor module two pots are included, one for trigger level setting and the other for setting sensitivity of the sensor. It allows to determine when a preset LPG gas level has been reached or exceeded. The module uses MQ-6 sensor to sense LPG leak. The MQ-6 can detect gas concentrations anywhere from 200 to 10000 ppm.
Interfacing with the sensor module is done through a 4-pin breadboard compatible SIP header and requires One I/O pin from the host microcontroller. The onboard microcontroller provide initial heating interval after power-up and then starts to measure LPG sensor output.If it found the LPG concentration above preset value , it will inform the Host controller by pulling the Output Pin to High and Starts to blink a onboard status LED. The sensor module is mainly intended to provide a means of comparing LPG sources and being able to set an alarm limit when the source becomes excessive.
The best location to fix Gas Sensor Module is near the Gas Cylinder or near the pipeline in case of piped gas connection. In case of LPG, when Gas leakage occurs , the gas will settle down near the floor because LPG is heavier than the air. So for best results it would be advisable to fit Gas Sensor Module nearly 1m above the floor.
