This paper introduces the pulse counting-speed digital speed can be measured in the 1000 / min speed following objects. The design uses a photoelectric sensor, the sensor is simple in structure, high precision, fast response, non-contact, reliable performance advantages. In signal processing using a 555-circuit when the Schmitt trigger, and multi-spectral oscillator, and 74 LS00, 74LS04 digital integrated circuits. Counter, and display drive circuit from three COMS-LED circuit CL102 portfolio composed of simple lines, low-cost, practical and workable. Overall, the counter is light weight, small size, low cost, and therefore widely used, which have a certain competitive in the marketplace.
Key words: sensors, triggers, multi-spectral oscillator, and integrated circuits.
