PVDF Piezoelectric Sensors for Seeds Counting and Coulter Clogging Detection in Sowing Process Monitoring

Figure 11

Signal with detected peaks marked, threshold = 2.5. Barley, 50 seeds delivered in batch. Blue lines show signal values, and the red lines denote the detection performed by the algorithm. It is possible to conclude that all significant events are counted, apart from one probable hit between 7.5-8 s. The figure proves the algorithm's capability to distinguish recoils from original hits for more accurate counting.
