Advanced Coal Mine Safety Monitoring and Auto Alert system using LoRa Technology

Abstract

Abstract: Coal mining poses several environmental challenges.  There are many problems associated with coal mine accidents, land subsidence, and mining waste disposal. Environmental pollution is one of them. Our proposal addresses these issues. Our device is designed to monitor and analyze temperature, humidity, pressure, and other related parameters in an underground coal mine using the Lora protocol and a Nodemcu esp8266 controller. ESP32 camera takes a picture that is sent to authorized recipients.

By using SMTP (simple mail transfer protocol), an individual can send emails to the server. The Nodemcu esp8266 is used in conjunction with a temperature and smoke detector as well as a gas detector to sense the mine's climate parameters and Wi-Fi to send the parameters to Thing Speak, then the OLED display (organic light-emitting diode) will show all sensor values. We must design a cost-effective and reliable device for the solution. To create a device that will ensure the lives of coal miners.
