| Abstract: | The counting device, with infrared pyroelectric sensor as its detection element, MCS -51 SCM as its controller, was used to detect and judge human motion and direction and statistics. The principles, hardware circuit, software design, fixing and debugging of the device were expounded. Its simple structure, reliable performance and low - cost contribute to the application in statistics in meeting places, classrooms or on buses. It takes on good prospects in the future. |
