Safety for Underground Coal Miners using ZigBee
designed a system i.e Smart Helmet for Coal Miners using Zig Bee which alerts the user from environmental changes in the surroundings such as temperature, gases and humidity. In this proposed system we use three types of sensors namely smoke sensor or MQ2 gas sensor which detects CO 2, methane, propane, i-butane, hydrogen fumes.
