<p>A sensing system for recognizing a direction of a moving body is provided to control an electric device applied to a specific space according to a recognized result for entrance and exit of the moving body. In a sensing system for recognizing a direction of a moving body, a first moving body recognizing sensor(210) is arranged at an entrance part or an adjacent part of a specific space. A second moving body recognizing sensor(220) is arranged at an inner part from regions where the first moving body recognizing sensor(210) is arranged. A control unit(100), connected with the first and second moving body recognizing sensors(210,220) by wire or wireless, recognizes an entering of the moving body when a moving body recognizing signal of the second moving body recognizing sensor(220) is not received at last after the moving body recognizing signals of the first and second moving body recognizing sensors(210,220) are received simultaneously or for a predetermined time together. The control unit(100) recognizes an advance of the moving body when the moving body recognizing signal of the first moving body recognizing sensor(210) is not received at last after the moving body recognizing signals of the first and second moving body recognizing sensors(210,220) are received simultaneously or for a predetermined time together.</p> |
