GAS INDICATOR USING LCD ARDUINO

detect LPG Gas. When LPG gas leakage sensed, it will give a HIGH pulse on its DO pin and Arduino constantly reads its DO pin.

When Arduino receives a HIGH pulse from the LPG Gas sensor module it displays the“LPG Gas Leakage Alert” message on 16x2 LCD and stimulates buzzer which beeps again until the gas detector module doesn't recognize the gas in the environment. 

When Arduino gets a LOW pulse from the LPG Gas detector module, then LCD will show the“No LPG Gas Leakage” alert message.

Arduino manages the complete process of this system like reading LPG Gas sensor module output, sending a message to LCD and stimulating buzzer. We can set the sensitivity of this sensor module by inbuilt potentiometer located on it.
