TEMPRATURE, HUMIDITY & FIRE EXTINGUISHER MONITORING USING ESP32 WEBSERVER

Abstract: Industrial environments such as warehouses, chemical plants, and manufacturing units require continuous monitoring to prevent fire accidents and ensure safety. Traditional fire detection systems often provide limited real-time monitoring and lack remote accessibility. This research proposes an IoT-based industrial fire safety monitoring system using the ESP32 microcontroller. The system integrates multiple sensors including a DHT11 temperature and humidity sensor, flame detection sensor, and infrared (IR) sensors for monitoring fire extinguisher status at different pillars. The ESP32 processes sensor data and hosts an embedded web server that displays real-time environmental conditions through a browser-based dashboard.

When abnormal temperature or flame detection occurs, the system activates a buzzer alarm and generates visual alerts on the monitoring interface. The proposed system offers a low-cost, scalable, and real-time monitoring solution that improves industrial safety and enables early fire detection.
