  One of the most important parts of business, especially in the coal mining
sector, is industrial safety. Suffocation, gas poisoning, object falls, roof
collapses, and gas explosions are among the risks associated with underground
mining. Therefore, air quality and the detection of hazardous events are
crucial in the mining business. This technology offers a wireless sensor
network so that base stations can keep an eye on the situation in underground
mines in real time. It offers temperature and dangerous gases including CO,
CH4, and LPG real-time monitoring. The main cause of mining deaths is that when
they fall and lose consciousness for whatever reason, medical attention is not
given to them in a timely manner. In order to solve this issue, the system
sends an emergency notice to the supervisor in the event that a person falls
down for any cause. Some employees are negligent when it comes to safety and
don't wear helmets. Then, a miner's helmet removal status was successfully
determined using a Limit switch.
