Development of Feeding Rate Detection Sensor Based on Wireless Technology

Abstract:

Feeding rate measurement is one of the most critical technologies in precision agricultural system. In present study, a wireless sensor was constructed to detect the feeding rate for corn combine harvester. Torsional strain gauges were fixed in the modified sprocket at header auger to measure the flow rate of collected corn in a form of torque. The force change was then transformed into voltage signal, which could be transmitted by Zigbee wireless module integrated in the sensor. To evaluate the reliability of the sensor, field study was conducted to develop a model between feeding rate and wheel torque. Obtained results showed that the developed sensor could detect the change of feeding rate, and further work should be conducted to calibrate the accuracy of the sensor.
