Abstract
In this paper, the coal mine safety system is implemented. With the emergence of Industrial Internet of Things (IIoT) a smart safety jacket is developed which will monitor the miner’s health and also provide precautionary measures for miner’s safety using concept of IoT. Integrating smart safety jackets with different health sensors such as pulse sensor, temperature sensor, blood pressure sensor, Electroencephalogram (EEG) sensor and then connect it with NodeMCU which is a Wi-Fi module and connect it with the internet. Sensors constantly send the sensor data to the cloud and if any abnormal situation occurs it will send a message to the responsible person in the control room as well as it will alert the miners. As, mining take place deep underground it can be more vulnerable to toxic gases, low oxygen level, hazardous gases can be detected with MQ gas sensor family. The developed system is mainly implemented to improve the working condition inside the coal mines and also to ensure workers safety.
