Abstract
The main point of concern in any industry is the safety of workers working in that industry. If we do study on the coal mines, safety of workers is considered as main part of management .For this, we have designed a device to give safety to the workers against the accidents in the coal mines. We have designed a helmet which is working on three parameters. It consists of two main sensors which are used to detect carbon monoxide and temperature inside the coal mine. The next is the GPS module which is used to locate the position of the worker in the coal mines.for wireless communication HC12 transmitter and receiver section is used. The display screen is used to read these parameters. The buzzer is used to give alert indication under harmful and dangerous condition.
