A Review on IoT-Based Smart Gas Leakage Detection and Alert System Using Robotic Automation(BOT)

– Gas leaks are a serious concern in residential and industrial settings, as they can lead to accidents and property damage. Traditional detection methods relying on human observation are often slow and unreliable. To address this, the proposed IoT-based robotic gas leakage detection system provides an automated, real-time monitoring solution. It integrates an MQ-3 gas sensor with a NodeMCU ESP8266 microcontroller and IoT connectivity to detect hazardous gas levels promptly. The robotic car continuously patrols the area, collects sensor data, and transmits it to cloud platforms and mobile applications for remote monitoring. If gas concentrations exceed the threshold, the system triggers a buzzer alarm and sends SMS alerts to authorized personnel. A web application also enables data tracking, ensuring efficient safety management. This integrated setup offers a reliable, cost-effective solution that reduces human involvement and enhances safety across residential, industrial, and commercial environments.
