Building object counting device with infra - red sensors

Abstract

My thesis is design a pipe device to count go-though objects. It can be applied in medicine factories to count number of pill board. Infra-red sensors were attached to one end of a composite tube. As an object moves over the infra-red sensors it will sense the existent of the object and send a signal to the MCU for counting purpose. The result will be presented on a LCD screen.
