This project is a Gas Leak Detection System designed to detect the presence of gas leaks in the environment using an MQ-2 gas sensor. Upon detection of a gas leak, the system triggers an audible alarm, displays a warning message on an LCD screen, and activates an LED indicator to signal the detection. This system aims to enhance safety by providing an early warning to prevent potential accidents.
- LM044L (LCD Display): Monochrome LCD display module with a 4-line by 20-character display, used for displaying text readouts.
- Buzzer: Audio signaling device that emits sound when activated, used for alerting and notifications.
- Arduino Simulino Uno: Simulated version of the Arduino Uno microcontroller used for virtual prototyping and testing.
- Relay: Electromechanical switch used to control a high-power circuit with a low-power signal.
- LED: Light Emitting Diode used for visual indication.
- Logic State: Refers to the binary condition of a digital signal (high or low voltage level).
- MQ-2 Gas Sensor: Versatile sensor used for detecting a range of gases including methane, propane, hydrogen, alcohol, smoke, and carbon monoxide.
- Initialization: Upon powering on, the Arduino initializes all components. The LCD displays a welcome message indicating that the gas leak detection system is active.
- Gas Detection: The MQ-2 gas sensor detects the presence of gas. When the logic state is high (gas detected), the sensor's analog output is read by the Arduino.
- Alarm Activation:
- Audible Alarm: The relay is activated, powering the buzzer which produces a loud sound.
- Visual Indicator: The LED turns on.
- LCD Message: The LCD displays a warning message indicating a gas leak.
