Yield monitoring system is one of the important components in precision agriculture. Unfortunately, there is no commercial yield monitoring system available for citrus mechanical harvesters to date. Most of the large equipment manufacturer investments are focus on developing the efficiency of their machine but has little investment or none at all in research and development of yield monitoring system for these high value crops. A yield monitoring system using impact plate has been developed that uses the impact of the fruits to correlate to its mass. The system performs well in both laboratory and field tests but due to the impact created by the oranges falling on the plate, the durability of the system is less. A non-contact method of collecting yield data will be very desirable to either augment the performance of the current system and eventually replaced it.
