GAS LEAKAGE DETECTION SYSTEM

MATERIAL USED

• ARDUINO UNO R3
• 16×2 LCD DISPLAY
• MQ-2
• MQ-135
• MQ-6
• 10K POTENTIOMETER
• BREADBOARD

WORKING

In our proposed system, the whole device is controlled though microcontroller that is Arduino UNO R3(ATMEGA-328)

• First of all, our microcontroller calibrates all the sensor so that they perform well.

• Then sensor senses the value of gases in the air and provide the value to our Arduino.

• Then our Arduino justifies and calculate all values into PPM (Parts Per Million) and display the values through 16×2 LCD display

• Then our Arduino justifies that if whether any value is increasing more than the average value. If that happens then our Arduino checks which gas has more concentration in air than average concentration of that gas. And provide us a alert that that a particular gas is getting leaked by showing it in our computer.

LEGAL NOTES

Don't use this project without giving me credits, this whole project was made for Jawaharlal Nehru National Science Exhibition when i was in 9th grade, it took a lots of efforts to develop this whole thing.
