Optimization of yield monitoring in harvest using a capacitive proximity sensor

초록

This study describes the process of applying the proximity sensor technology to measure grain flow during harvest in real fields. The results of the present study can eventually lead to the accurate prediction of harvest. In the experimental combine, the grains flowed through an elevating screw into the grain tank. The flow was monitored for the amount of grain via the attached proximity sensors. The results show a high correlation (R2= 0.996) between the signal detection time and the feed amount. The high correlation of the equation obtained in the present study proves the feasibility of the system and demonstrates its potential in terms of making a considerable contribution to precision in agriculture practice. ? 2016 Asian Agricultural and Biological Engineering Association, Published by Elsevier B.V.
