Remote Monitoring of Hazardous Environment at Mining Sites Using LoRa Network

Mining sites are hazardous, with risks from poisonous gases, fires, and other dangers threatening worker safety. To address these risks, a remote monitoring system using a LoRa (Long Range) network is proposed. This system provides real-time monitoring and alerts to enhance safety.The system features an Arduino-based unit with a gas sensor, fire sensor, and DHT11 sensor. These sensors collect data on environmental conditions, fires, and gas presence. Data is transmitted via a LoRa transmitter (LoRa TX) to a receiver (LoRa RX) connected to an ESP8266 module, which communicates with a central station. Alerts are sent to authorities through GSM, and a local buzzer warns workers of immediate dangers.The system operates by continuously monitoring for hazardous conditions, sending data to the central station via LoRa. If an emergency is detected, the ESP8266 processes the data and triggers the GSM module to send SMS alerts. A buzzer also provides on-site warnings.Leveraging LoRa for long-range communication and GSM for critical alerts, this system offers a comprehensive safety solution, reducing mining risks and ensuring timely intervention during emergencies.
