This kit Gas Leakage detection system(https://www.kitsguru.com/final-year-engineering-projects/automation-projects/gas-leakage-detection-auto-off) helps you to upgrade your safety standards, comply statutory requirements on environmental commitments and most important and basic function being prevent accidents and protect life and property from disaster. In this kit we used MQ-6 sensor for gas leakage detection. The heater provides necessary work conditions for work of sensitive components. The enveloped MQ-6 has 6 pin, 4 of them are used to fetch signals, and other 2 are used for providing heating current.
In the kit Gas Leakage System here MQ-6 sensor works on basics of combustion process, and output is given in variable voltage (analog variation voltage) form, so, when LPG gas is leakage voltage at the output pin of MQ-6 is increased and we use a Op-amp IC LM324 as a comparator for compare the LPG leakage with respect to normal condition.
In the kit Gas Leakage System output of comparator is fed to microcontroller (AT89S8253) and corresponding coding LCD is display gas leakage and gives another instruction to stepper motor via motor driver IC (L293D) to drive the stepper motor to turn off the regulator of gas and a buzzer is beeping continuously in GAS leakage condition. This kit are used in gas leakage detecting equipments in family, Car and industry, are suitable for detecting of LPG.
