HUMAN BODY MOVEMENT DETECTION DEVICE AND DETECTION DEVICE FOR NUMBER OF PASSING PEOPLES

摘要

PROBLEM TO BE SOLVED: To provide a human body shift detection device and a detection device for the number of passing peoples, which can easily, highly precisely and inexpensively detect a human body and the number of passing peoples with high reliability and which can accurately detect the number of passing peoples at the gateway of wide width. SOLUTION: A sensor head 41 detecting a human body 45 installed at the upper part of the gateway 44 a room and a signal processing circuit 42 setting a threshold based on a floor surface temperature detected by the sensor head 41, judging the existence of the human body when the output value of the sensor head 41 detects rise/fall against the threshold and judging movement between the elements of the sensor head 41 of the detected value are provided.
