| Abstract: | In this paper, a rotation speed measurement system using the AT89C52-MCU was designed based on infrared, A pair of infrared emitted and reeeive diodes were used to form light beam, when the gear teeth broke the light beam at intervals, the eleetronie pulse was generated. The MCU eount the time which the pulse spend through the way of the synchronization M/T and then compute the rotation speed. The experiment show that the measuring instrument has a high accuracy and measures real-timely, and it can measure the low and high rotation speed. |
