This study aims to investigate the relationship between elderly monitoring system data and climate condition, and to investigate the difference of reaction to the climate condition caused by the cognitive function, motor function and self-rated health. Four pyroelectric sensors are set at 15 elderly persons' home, and the sensors can detect the subject's movement in their house. Correlation between their total activities at home and the climate conditions is calculated considering the difference by the health conditions. Correlation between total activities and average temperature showed moderate correlation (R=-0.41). Comparing between higher cognitive function group and lower cognitive function group, high group showed moderate correlation (R=-0.43), but low group showed little correlation (R=-0.25). On the other hand, in high group, their total activities are not much changed by weather, but in low group, their total activities in rainy days are about 5 % lower than that in sunny or cloudy days (p=0.05). These results give us suggestions about seasonal changes or person specific patterns are related to the change of the cognitive functions. More information about the activities in or out of their home may help earlier detecting the change of health conditions.
