A Koji Temperature Monitoring System

摘要

This paper proposes a temperature monitoring system as an IoT application. The system is designed for temperature monitoring of koji which is an important material for sake, Japanese rice wine, brewing and investigating brewing environment. The system has been installed in a brewery and is being used to monitor koji making from steamed rice and koji mold to finished koji. We demonstrate that koji temperature transition can be observed in real time and logged by the system.
