The MQ2 sensor continuously monitors LPG gas concentration. If the gas concentration exceeds the threshold, the system activates the buzzer, turns on the red LED, displays an alert on the LCD, and energizes the relay.
The HX711 module measures the cylinder weight using a load cell and displays the weight through the Serial Monitor.
