Nursing-care facilities, such as specialized facility of fee-based homes for the elderly, have nurse call buttons in residents’ rooms. Nurse call systems are usually used by residents to call workers at the facilities. In this paper, we regarded the nurse calls as sensors that form a sensor network installed in the nursingcare facilities. We then conducted a long-term consecutive measurement of nurse calls at 15 facilities measuring nurse calls by residents for seven months, and analyzed monthly and diurnal variations in the number of nurse calls activated. As a result, we found no seasonal variation in average numbers but did find diurnal variations related to the schedules of facilities. We also clarified four kinds of characteristics of residents.
