ZIGBEE SMART SAFETY WAIST

Abstract

Safety monitoring systems have become increasingly important in modern healthcare and industrial environments, especially for individuals working in hazardous conditions. Workers such as miners, construction laborers, firefighters, and rescue personnel are often exposed to dangerous environments where sudden health problems, environmental changes, or accidents may occur. Continuous monitoring of vital health parameters and environmental conditions is necessary to ensure their safety. Therefore, the Zigbee Smart Safety Waist System is designed to monitor a person’s health conditions and transmit emergency alerts to a remote monitoring station. The proposed system is built around the ESP32 microcontroller, which acts as the central processing unit. Several sensors are integrated into the wearable device to monitor the user’s condition. The DHT11 sensor measures temperature and humidity levels, while the SpO2 sensor monitors blood oxygen levels and pulse rate. A vibration sensor is used to detect sudden movements, impacts, or falls that may indicate an accident. In addition, a GPS module is used to track the real-time location of the user. The collected data is processed by the ESP32 and displayed on an LCD display for local monitoring.For wireless communication, the system uses Zigbee technology to transmit sensor data from the wearable device (transmitter module) to a remote monitoring station (receiver module). At the receiver side, another ESP32 processes the received data and displays the information on an LCD screen. A buzzer is activated when abnormal conditions are detected, providing immediate alerts. The system also integrates IoT technology to enable remote monitoring through internet-based platforms.By combining wearable sensors, wireless communication, and IoT monitoring, the proposed Zigbee Smart Safety Waist system provides an efficient solution for real-time health monitoring and emergency alert generation, thereby improving the safety and protection of workers in hazardous environments.
