In rearing at a factory, the development of a system for control of the rearing environment is an important. In this study, we evaluated measurement control system, consisting of a personal computer, temperature and humidity sensors, recorder, and signal conversion interface, for a silkworm rearing room. With the system, it was possible to set the optimum temperature and humidity automatically according to a schedule (hour and day) as well as display the indoor and outdoor temperature and humidity on the CRT screen. In addition, the deviation between a target value and the measured value was decreased by the temperature and humidity feedback control based on the measured data on the silkworm rearing position.
