Intelligent Helmet Safety System for Mine Workers

This project proposed an embedded system for mine worker's safety purpose using ARM7.A smart helmet has been developed that is able to detection of hazardous events in the mines industry. In the development of helmet, we have considered the four main types of hazards such as air quality, temperature and humidity and smoke detection. The first is the level of the hazardous gases such as methane, Butane, etc. for which MQ4 gas sensor is used. The second hazardous level is a temperature to measure temperature LM35 is used .Third level is humidity in the mine, to measure humidity HSM-20G is used. The fourth hazardous level is smoke detection for smoke detection MQ2 sensor is used. Thisdata will be transmitted to the control room through zigbee wireless network. If these parameters crossed their limit, it will alert the workers by turning ON the buzzer which is situated on helmet then information can provide tocontrol room using zigbee transmitter and receiver. When buzzer is on the mine workers haveto chance to safety his life from the hazards levels occursin coal mines
