Smart Helmet for Coal Miners using Zigbee Technology
This project focuses on a mine supervising system which is based on the cost effective Zigbee system. Our project aims at developing a wireless sensor networks, realized real time surveillance with early warning intelligence on harmful gases, temperature, humidity in mining area and used zigbee communication to reduce potential safety problems in coal production using a Zigbee wireless technology. All these three parameters are detected continuously by temperature sensor, gas sensor, humidity sensor and if they cross the pre defined limit, then the user gets alert as the buzzer will automatically turn on with LED indications. With a zigbee Wireless positioning devices the system might be easily extended. The values of different sensors are continuously transmitted by zigbee transmitter to the remote monitoring unit which are received by zigbee receiver module.
