Yield monitoring and mapping is more effective for small farmers on farm management practices. The objectives of the study were to investigate the Chinese cabbage yield monitoring correction under tilt situation through various belt conveyor speeds during unloaded and loaded conditions and to verify the accuracy of the system. Two sets of dual-axis angle sensor were attached at the left top and bottom on an inclined cabbage collector frame. A load cell was installed at the conveyor outlet for the precision of yield sensor by the same method of angle sensors. Ten pieces of Chinese cabbage were randomly used for the test. The conveyor was driven by a 0.2 kW DC motor with different speeds of 0.05, 0.10, 0.15, 0.20 and 0.25 m/s. Measured angles in x-y direction and weight versus time were recorded. During the unloaded and loaded conditions, the standard deviation of measured tilt angle in x-y direction were 1.33o, 1.20o and 0.18o, 0.72o, respectively. It showed that tilt sensors were capable of detection with good accuracy. Any increase in conveyor speed showed positive correlation (R2=0.99) with cabbage yield. The range of tilt angle depends on various weight of cabbage and conveyor speed. The system can help stability prediction of the machine according to the agricultural working conditions.
