Development of Coalmine Safety System Using Wireless Sensor Network
In the Era of embedded technology, the Zigbee protocols are used in more and more applications. Because of the rapid development of sensors, microcontrollers, and network technology, a reliable technological condition has been provided for the automatic real-time monitoring of coal mine. The application designs a monitoring system for coal mine safety based on Zigbee wireless sensor network. The underground system collects temperature, humidity and methane values of coal mine through sensor nodes in the mine; it also collects the number of personnel inside the mine with the help of an IR sensor, and then transmits the data to information processing terminal based on ARM.
