Counting detection for a small grains by using light screen sensing method ( Hardware )
광막센싱방법을 이용한 미소물체의 계수검출 (하드웨어)
초록
In this paper, the light screen sensing system is introduced and testified to detect small grains such as seeds or electronic chips of uneven sized. Two modules composed of transmitter-receiver sensor array and microprocessor-based sensor signal processing system are developed to realize the proposed system. Experimental results showed that the sensing signal was relatively clear and its counting performance was very stable.
