Abstract

Several studies has reported that indoor air quality affects concentration and memory. For this reason, air quality control services has been required indoors, such as offices, schools and homes. For effective air quality control, not only conventional temperature and humidity adjustment, but also removal and addition of gas (odor) are important. To control gas (odor) concentration with high precision, gas sensors are required. In this report, we propose a compact photoacoustic optical gas sensor utilizing resonant cell with frustum hole for indoor air quality control.
