The IoT-Based Smart Industrial Worker Safety System is a wearable safety solution designed to improve the protection of workers operating in hazardous industrial, sewage, and confined environments. The system uses an ESP32 microcontroller as the central processing unit and integrates MQ-135 and MQ-2 gas sensors for detecting harmful gases, smoke, and combustible gases, while the DHT11 sensor monitors temperature and humidity. An MPU6050 motion sensor is used to identify sudden movements and possible fall incidents. In an emergency, the worker can also manually activate an SOS push button. The detected conditions are processed by the ESP32 and indicated locally through an OLED display, buzzer, and LED. At the same time, the system uses IoT connectivity and a Blynk dashboard to provide real-time monitoring and emergency notifications to the supervisor. This enables faster identification of hazardous conditions and worker accidents, allowing timely rescue and safety actions. The proposed system provides a compact, practical, and modular approach for enhancing industrial worker safety.
