The Development Of A General Purpose Optical Counting Device
Keywords:
Science, Engineering, optical counting device, numberAbstract
Accurate determination of the number of occurrence of a particular event is of significance in the field of science and engineering and to some extent, in the field of the social sciences. This experiment was on the development of an optical counting device that can be used in the determination of the number of occurrence of an event in any of these fields. The device is based on sensing the obstruction of light intensity by the object(s) to be counted and has facility for storing and displaying the total number of occurrence of the event(s).
