1. GAS LEAKAGE DETECTION SYSTEM WITH AUTOMATED REGULATOR

2. Abstract The Gas Leakage Detection System with Automated Regulator is designed to detect gas leaks and automatically shut off the gas supply, preventing potential hazards. This system uses an Arduino Uno microcontroller, a gas sensor, a servo motor, and other components to monitor gas levels and respond appropriately to ensure safety. Upon detecting a gas leak, the system closes the gas regulator, activates a fan to disperse the gas, and provides visual and auditory alerts. This project aims to enhance safety in environments where gas is used by providing an automated response to gas leaks.

3. Existing System Existing gas leakage detection systems are generally simple setups that only provide an alarm when a gas leak is detected. These systems often rely solely on sensors and buzzers to alert individuals of a gas leak, leaving it up to them to manually turn off the gas supply. There is little to no automation involved in handling the gas flow once a leak is detected, which can delay the response and increase the risk of accidents.

4. Disadvantages of Existing System 1. Manual Intervention Required:The existing systems require manual intervention to shut off the gas supply, which can be dangerous and slow in an emergency. 2. Limited Alert Mechanism : Many systems only include a buzzer or alarm, which may not be sufficient to alert everyone in the vicinity, especially in noisy environments. 3. No Gas Dispersion Mechanism:The existing systems do not have any mechanism to disperse the leaked gas, which can lead to accumulation and increase the risk of explosion. 4. Potential for Human Error : Depending on humans to shut off the gas can lead to errors or delays, especially if the person is not nearby or unaware of the leak.

5. Proposed System The proposed system enhances safety by automating the response to gas leaks. It includes a gas sensor that detects leaks and an Arduino-controlled servo motor that automatically closes the gas regulator. Additionally , the system provides both visual and auditory alerts through LEDs and a buzzer, and it activates a fan to disperse the leaked gas. This automation reduces the need for human intervention and ensures a faster, more reliable response to potential gas hazards.

6. Advantages of Proposed System 1. Automated Gas Regulation:The system automatically closes the gas regulator upon detecting a leak, reducing response time and preventing accidents. 2. Comprehensive Alert System : The combination of LED indicators and a buzzer ensures that everyone in the area is alerted to the danger. 3. Gas Dispersion : The small fan helps to disperse the gas, lowering its concentration and reducing the risk of an explosion. 4. Increased Safety : By automating the critical safety responses, the system minimizes the potential for human error, thereby significantly enhancing safety.

7. Hardware Requirements 1. Arduino Uno: The microcontroller that acts as the brain of the system. 2. Gas Sensor (MQ-2/MQ-6 ): Detects the presence of gas. 3. Servo Motor : Controls the gas regulator to shut off gas flow. 4. Gas Regulator: Regulates or shuts off the gas supply. 5. LEDs : Visual indicators for system status. 6. Buzzer: Provides an auditory alert when a gas leak is detected. 7. Small Fan: Disperses the leaked gas to reduce its concentration. 8. Power Supply: Powers all the components.

8. Software Requirements 1. Arduino IDE: For programming the Arduino Uno. 2. Embedded C/C ++: The programming language used to write the code that controls the system. 3. Fritzing/Proteus: For circuit design and simulation (optional but useful for testing before implementation). 4. Libraries: Specific libraries for controlling the servo motor and interfacing with the gas sensor.

9. Conclusion The Gas Leakage Detection System with Automated Regulator provides a significant improvement in safety for environments where gas is used . By automating the response to gas leaks, including shutting off the gas supply and providing immediate alerts, the system minimizes the risk of accidents due to gas leaks. This project demonstrates the effective use of microcontrollers, sensors, and actuators in creating a robust safety system that can be deployed in homes, kitchens, and industrial settings.
