HUMAN BODY DETECTOR

摘要

PROBLEM TO BE SOLVED: To improve detecting accuracy by correcting the background temperature by a monitoring sensor without an independent background temperature measuring area for correcting in a human body detector used in monitoring the interior of a toilet of a hospital or a home for the aged. SOLUTION: Plural infrared ray detecting sensors are disposed to divide a monitoring area and monitor the same, and according to the change of output of the sensor not detecting the human body, entering/leaving determination is corrected to obtain high detecting accuracy.
