초록
In this study, we develop a methane sensor module that can detect low concentrations below 5,000 ppm and measure up to the detec- tion limit of 50 ppm with the NDIR method, with a long lifetime and high accuracy. Methane (CH4) is one of a representative green- house gas, which is very explosive. Thus, it is important to quickly and accurately measure methane concentration in the air. To adjust the methane sensor for industrial field applications, a NDIR-based small sensor was implemented and characterized, where its volume was 4 cm × 4 cm × 2 cm and its response time (T90) was less than 30 sec. These results demonstrate that the proposed sensor is commercially available for low-concentration measurement, low volume, and fast response application, such as IoT sensor nodes and por- table devices.
