IoT-Based Gas and Smoke Detection System using Blynk application with Automatic SMS and Alarm Notifications

Abstract

The Internet of Things (IoT) has revolutionized safety and security by providing innovative solutions to critical challenges. Gas leakage, a dangerous chemical from petroleum, can cause health issues and disrupt workspaces. To prevent such accidents and maintain a clean air environment, a monitoring gas leakage detector system is proposed. The system uses a NodeMCU ESP8266 Wi-Fi microcontroller and a combustible gas sensor (MQ-2) to detect the presence of propane, butane, and Liquefied Petroleum Gas (LPG). The sensor's voltage output determines gas concentration, and the ESP8266 sends data to the blynk application. This system aims to maintain a clean and safe workspace. The IoT-based gas and smoke detection system uses sensors and a mobile app to monitor premises remotely. It sends SMS alerts to users and authorities in case of incidents and activates audible alarms to the users. This system enhances security by reducing risks and reducing the need for manual monitoring, making it a significant step towards safer environments.
