Smoke Detection Security Using ESP8266

Fire accidents continue to pose a serious threat to human life and property, highlighting the importance of reliable and rapid smoke detection systems. Conventional smoke detectors are effective within a limited range but lack the ability to provide real-time alerts to users at remote locations. To address this limitation, this paper presents an IoT-based smoke detection system using the ESP8266 microcontroller. The system integrates a gas sensor for smoke detection and utilizes the Wi-Fi capability of the ESP8266 to send instant notifications to a mobile application. In addition, a local alarm is activated to ensure immediate awareness of nearby occupants. The designed system offers an affordable and expandable solution that can be effectively deployed in both smart homes and industrial environments.”. Experimental results demonstrate that the system is capable of detecting smoke promptly and providing timely alerts, thereby enhancing safety and reducing potential risks.
