| Abstract: | It describes a design of velocimetry by Hall elemnts in this paper.With the design,pulses produced by the interaction of A1302 and magnetic steel were converted into voltage signal through a frequency / voltage conversion circuit,furtherly converted into digital signals by AD,then speed signals were processed in the single chip and displayed. |
