Abstract
The aim of the project is to design a wireless helmet for coal miners using ZigBee wireless mine supervising machines. Nowadays coal miners are facial various problems. Workers safety in underground coal mines has always remained a challenging task. Several fatal and non-fatal accidents take place worldwide resulting in causalities and injuries of coal miners. Study aims to develop a wearable safety device comprising of gas sensor, temperature sensor, oxygen sensor, opguard, ultrasonic sensor, ultraviolet sensor. The values of different sensors are continuously transmitted by wireless transmitter to the remote monitoring unit which is placed outside the mine and received by the receiver module (PC).
