The smart helmet concept designed for enhancing coal miners' safety demonstrates a well-considered approach. It integrates a variety of sensors and cutting- edge communication technologies to ensure components. The environmental conditions within the mine are monitored by sensors such as the DHT11, which tracks temperature and humidity, and the MQ-02, which detects harmful gas concentrations like methane and carbon monoxide. A vibration sensor is also utilised to identify any unusual movements or shifts that might indicate potential structural instability. The device's communication system is notably robust. LoRa technology, known for its extensive range and low power consumption, is used to transmit data over significant distances, especially the well- being of miners working in coal mines. The device functions through a combination of several key in areas where conventional communication methods like Zig-bee might fall short. Additionally, GSM technology serves as a backup communication channel in case LoRa connectivity is compromised. The core data processing unit is an Arduino microcontroller.
