What is the role of optical/photoelectric sensors in yield monitoring?

Optical/photoelectric sensors play a critical role in yield monitoring by estimating the volume of harvested products. These sensors work by emitting a light beam that interacts with the crops as they pass through the sensing area, typically in harvesting machinery. When the light beam is interrupted or reflected by the crops, the sensor can determine the amount and density of the material. This information can be used to calculate the yield based on the volume of product measured during harvesting.

This method provides a non-destructive way to monitor yields in real-time, enabling farmers to make informed decisions about harvesting and overall crop management. The use of light beams allows for quick assessments, which can be crucial for timely agricultural practices.
