Document Type and Number:
Japanese Patent JPH06274768
Kind Code:
A
Abstract:
PURPOSE: To provide a human body sensor system which can accurately decide the presence or absence of human beings by means of a human body sensor.
CONSTITUTION: A 1st sensor A is set at a gateway E' of a monitor zone E and detects the entrance/exit of human beings, and a 2nd sensor B is set in the zone E and detects presence of human beings.
