A high number of gas leaks occur every year at the industrial facilities. It may lead to diseases, deaths, damage of equipment and ecological incidents. We present the optical absorption infrared sensor for monitoring of the lower explosive limit of gases and vapors containing flammable hydrocarbon compounds, and the description of the sensor design and characteristics. The sensor is able to monitor up to 30 components and can be interfaced with an external device using MODBUS RTU protocol. Our design opens up wide opportunities for the indoor and outdoor gas monitoring applications for the petrochemical and oil processing industries and hazardous industrial facilities.
