To Monitor Real-time Temperature and Gas in an Underground Mine Wireless on an Android Mobile

Abstract

In an underground mine there are temperature variations as well as toxic gases are released which cause potential hazards for mine workers. Hence it is necessary to monitor and assess these parameters well in advance for the safety of mine workers. This research paper discusses the concept of real-time monitoring and assessing temperature and toxic gases which are released from underground mines. Methane (CH4) and Carbon Monoxide (CO) are the most prominent gases released in a typical underground mine. For precise detection of temperature variations and ppm values of gases; sensors can be used. This research work is an effort to
develop an instrumentation system built around PIC Microcontroller using Quartz Sensor / Crystal, for precise detection of temperature variations as well as Gas sensors for precise detection of Methane (CH4) and Carbon Monoxide (CO). Individual gas sensors are used to detect these gases, their corresponding ppm values are also measured. The temperature value being measured as well as the ppm values of these toxic gases are then transmitted wirelessthrough an WIFI module and displayed on an Android mobile.
