IOT BASED GAS LEAKAGE DETECTION AND AUTOMATION CONTROL

Abstract: Industrial gas leakage poses serious risks to human life, industrial assets, and the environment. Accidental leakage of toxic or combustible gases can lead to catastrophic events such as explosions, fires, equipment damage, and severe health hazards to workers. Therefore, early detection, continuous monitoring, and rapid control of gas leaks are essential to ensure industrial safety and minimize potential losses. This project, titled “IoT-Based Industrial Gas Leakage Detection & Automated Control,” proposes an intelligent, automated, and reliable system for real-time detection and management of hazardous gas leakage in industrial environments.

The proposed system employs sensitive gas sensors to continuously monitor the presence and concentration of harmful gases in the surrounding atmosphere. The sensor data is processed by a microcontroller equipped with internet connectivity. When the detected gas concentration exceeds a predefined safety threshold, the system immediately initiates automated safety actions. These actions include activating audible and visual alarms to alert nearby personnel and closing the gas supply through a servo motor-controlled valve to prevent further leakage. This automated response significantly reduces the dependency on manual intervention and minimizes reaction time during emergency situations.

In addition to local safety measures, the system integrates Internet of Things (IoT) technology to provide real-time monitoring and remote accessibility. Gas concentration data, system status, and emergency alerts are transmitted to a cloud-based IoT platform and can be accessed through a web or mobile application. This enables industry operators and safety authorities to monitor conditions remotely, analyze data trends, and take timely preventive or corrective actions even from distant locations.

The proposed system is designed to be cost-effective, energy-efficient, and easy to implement, making it suitable for both small-scale and large-scale industrial setups. By combining sensing, automation, and IoT-based communication, the system enhances workplace safety, reduces the risk of industrial accidents, and improves overall operational reliability. The solution can be effectively deployed in chemical plants, oil refineries, gas pipelines, storage facilities, manufacturing industries, and other hazardous environments where gas leakage detection and control are critical.
