WebSocket Based IoT Temperature and Humidity Monitoring System for Underground Coal Mine

In underground coal mines safety of the workers always has been a concern and challenging task. Excessive humidity and high temperature can easily be formed in the underground environment which can affect the health safety of the workers significantly. Typically, the temperature ranges from 27°C to 30°C in underground coal mine and humidity is spanned from 70% to 75% which is considered the maximum limit for the survival of any human being. Temperature and humidity can rise for various reasons, resulting in occurring serious accidents in the underground mine. And the situation becomes more severe because electronic devices hardly function properly at that high temperature and humidity level. To address this issue many manual systems are used in underground coal mines to measure and monitor temperature and humidity. But in the recent era with the advancement of communication technologies we can design more efficient systems instead of the former manual ones. So,this paper suggests a way to invent a monitoring device to prevent these accidents associated with humidity and temperature by developing a robust, sustainable and cost efficient electronic measurement system using state-of-the-art communication techniques. This paper aims for paving a way to construct a portable device using the Internet of Things (IoT) technique along with many other advanced techniques and services, such as embedded data mining, distributed storage, and alarm services at the edge of the network. Event triggering-based data transmission methodology is adopted to process the mine's real-time data. Moreover, decision making based on real-time data further enhances the utility of the proposed system.
