Abstract
Increase of CO_2 and PM2.5 concentration are serious problems. The technique which measures the gas concentration in the environment is very important. In addition, today, people who require care are five million in Japan. Therefore, the technique which measures the gas concentration in room can help the people require care. In this study, small gas sensor module which enables to communicate in wireless communication is developed. In this paper, we attempted to evaluate a characteristic of solid-state electrolyte type CO_2 sensor.
