A sensor circuit which is mounted in the helmet of each miner will observe the environmental changes also the pressure by which miner is affected. During the development of safety helmet we consider mainly 3 factors. First is the presence of dangerous gases, second is helmet removal by the miners and third one is miner hit by an object.

The mines that are deeper, the more dangerous it could be to be running jobs. There's oxygen leak that is restricted, and there are challenges related to leaving a mine if a crisis happen. So here we propose a mining tracking as well as safety system for the mining industry using microcontroller based circuit on the worker helmet.

A rebreather is a breathing apparatus that absorbs the carbon dioxide of a user's exhaled breath to permit the rebreathing (recycling) of the substantially unused oxygen content, and unused inert content when present, of each breath. Oxygen is added to replenish the amount metabolised by the user. This differs from open-circuit breathing apparatus, where the exhaled gas is discharged directly ...
