Coal Mine Safety Monitoring System Using ARM9

Coal is mined in every country which is mainly used to generate electricity. Thousands of mine workers were killed every year due to many disasters takes place inside coal mine. These accidents are caused mainly due to the leakage of poisonous gas [2] present in the mine. Especially developing countries face a poor safety system for mine workers. Hence it requires a safety monitoring system [1] provides safety factors and good decision making basis for underground environment. This paper provides a wireless monitoring system which provides a reliable communication even during disaster. The system has a underground system which collects temperature, humidity, methane gas and CO gas values and transmits it to the base station through Wi-Fi with a ARM9 core. Also this system provides online monitoring [3] by updating the values into a web server.
