Design and Implementation of an Internet of Things (IoT) Based Automatic Fire Fighting Sprinkler System

Abstract

The frequent incidence of fire accidents in homes, work places, industrial buildings and the limitations of conventional fire suppressor system demand the development of intelligent and responsive fire-fighting solutions. This research work, design and Implementation of an IoT based automatic fire  fighting sprinkler system is aimed at improving response time, reliability, and remote monitoring compared to conventional fire protection systems.  The system employs a combination of temperature, smoke and flame sensor interfaced with a microcontroller (ESP8266) to continuously monitor environmental conditions. When fire indicators exceed preset safety thresholds of above 60⁰C, the controller automatically triggers a sprinkler mechanism through a relay- driven solenoid valve to suppress the fire. In addition, the system transmits real-time alerts and sensor data to a cloud platform (Bylink) through a wireless communication module, allowing users to monitor conditions and receive notifications from remote locations. The prototype was developed using avoidable and energy efficient components and evaluated under controlled fire simulation. The result shows that the system responds promptly to fire events which activates the sprinkler effectively, and provides reliable real- time monitoring. The constructed IoT based fire- fighting sprinkler system demonstrates improved efficiency, scalability, and suitability for home and industrial fire safety applications.
