LPG Gas Leakage Sensor Alarm Circuit | Electronic ...

LPG Gas Leakage Sensor Alarm Circuit This circuit has been tested with LPG gas and was observed to do the job satisfactorily. Whenever there''s LPG concentration of 1000 ppm (parts per million) in the spot, the OUT pin of the sensor module goes higher. This signal drives timer IC 555, that is wired as an astable multivibrator. The multivibrator generally works as a tone generator.
