A Microcontroller Based smart helmet for coal miners for air quality and hazardous event detection

Electronics and Communication engineering

A classic model of smart helmet has been developed to assist miners working in the mining industry. Many dangerous events tend to occur in mining industry that can lead to life-threatening injury or to be fatal. Miners helmet is most commonly and compulsorily used. But it does not improve the safety of miners apart from providing illumination. A smart helmet has been able to detect all dangerous events with the help of sensors. Gas sensor will detect poisonous gases like CO, CH4, LPG and natural gases. Collision sensor will detect by which pressure miners will be affected by heavy object fall and IR sensor will detect whether helmet is removed or not. Data is transmitted wirelessly through RF module. Each sensor has critical value, if reached then buzzer will automatically switch on giving an alert signal to the miners and supervisors. Thus smart helmet prevents miners from suffering upcoming accidents.
