Abstract This work presents a compact and reliable system for monitoring the safety and environmental conditions of mining workers operating at high altitudes. The proposed prototype integrates multiple sensors with a NodeMCU microcontroller to continuously observe critical parameters that influence worker health and risk exposure. A flame sensor is employed to detect the presence of fire hazards, while a smoke sensor identifies harmful gases or particulate concentration in the surroundings. A vibration sensor is incorporated to recognize abnormal movements or ground disturbances that may indicate structural instability. Additionally, a DHT11 sensor measures temperature and humidity, which are essential factors in high-altitude environments.
All sensor data are processed in real time by the NodeMCU, enabling immediate analysis and response. When any parameter exceeds predefined safety thresholds, an alert is generated through a buzzer to notify nearby personnel. The system is powered through a stable supply unit, ensuring uninterrupted operation in remote locations. The design emphasizes low cost, ease of deployment, and adaptability to harsh mining conditions. This prototype demonstrates an effective approach to enhancing worker safety through continuous monitoring and early warning, thereby reducing the likelihood of accidents and improving overall operational reliability in mining environments.
Keywords Mining safety, high-altitude monitoring, worker safety system, NodeMCU, flame detection, smoke detection, vibration sensing.
