Abstract: The coal mine operations are very risky due to high temperature and different amount of different gas compositions in air underground coalmine. Due to this, there are so many accidents taking place which leads to killing many skilled workers and laborers. This definitely need a monitoring system to sense the gas concentration and temperature. In this paper we are developing a safety monitoring system for coal mine workers with NodeMCUs and IoT. In this system, we are using two NodeMCUs as a communicating device in which one is developed as wearable device (client) which always receives the information and the second one is used to gas and temperature sensor node(server) which always sends the alert to the client if the gas concentration is more at high temperature. We are developing a wearable device with NodeMCU which always gets the alert messages/alert buzzer and information regarding gas concentration and temperature. This system is a combined action of the temperature, humidity, some gas sensors and IOT module to detect all the information in the coal mine and log all the data into cloud and communicate with the workers wearable device to send the information(alert messages if any accident is about to happen) continuously.
