This paper presents an autonomous remote monitoring module for measuring the concentration of toxic gases in mines. The system uses temperature and humidity sensor DH11, MQ-2 sensor for detecting methane, MQ-7 for measuring the concentration of carbon monoxide and MQ-135 for measuring the concentration of carbon dioxide. Constituent parts of the module are Arduino board and ESP8266 Wi-Fi module capable for TCP/IP connections. The main advantage of this low cost prototype is the possibility to be used instead of sophisticated equipment that is often unaffordable for many mines in developing countries. The proposed system has been tested during an explosion at the surface mine Strmosh in Probishtip and has proven to be suitable for deployment in underground mines.
