Now a day's every system is automated in order to face new challenges. In the present days Automated systems have less manual operations, flexibility, reliability and accurate. Due to this demand every field prefers automated control systems. Especially in the field of electronics automated systems are giving good performance.   This project is useful in industries.  The project “GAS LEAKAGE ALERTING SYSTEM FOR INDUSTRIES” itself indicates that whenever any leakage of dangerous gases occurs in the industries so that it will indicate through the buzzer.  In this project we are using the mq-4 sensor that can detect Methane, CNG Gas and finds the leakage of gases in an industry. This project is designed around a microcontroller which forms the control unit of the project.   The microcontroller gets the information regarding the leakage of any gas through the gas sensor and alerts about the condition being sensed using Buzzer and turn ON the exhaust fan automatically.  By this way we can take the prevention steps before occurring the major fire accidents and we can avoid the human losses and financial losses.

 

This project objectives are:

• Automatic gas leakage detection.
• GAS detection alerts using BUZZER.
• Automatic turn of exhaust fan to expelled the gas outside.
• Visible alerts using LED.

The major building blocks of the project are:

• Regulated power supply.
• PIC Microcontroller.
• Crystal oscillator.
• Reset.
• Mq-4 Gas sensor.
• Buzzer with driver.
• Relay.
• Exhaust fan.
• LED Indicators.

Software’s used:

• PIC-C compiler for Embedded C programming.
• PIC kit 2 programmer for dumping code into Micro controller.
• Express SCH for Circuit design.
