The sorting system is a key link in the logistics industry,  Traditional sorting work is manually completed with high labor intensity and easy to make mistakes. With the continuous progress of technology, automated sorting has become a new trend and sensors are one of the important components of automated sorting.
The role of sensors in object detection
Sensors in the sorting system can be used for item detection. Sensors can detect the presence of items, their shape, features, and other information to determine the exact location of the item, which is then captured and sorted to the corresponding area using a robotic arm. 
The role of sensors in size detection
Sensors can also be used to measure the size of items. The sensors in the sorting system can obtain accurate size information of items and compare it with preset standards to determine whether the items meet the requirements, in order to achieve automated sorting.
The role of sensors in weight detection
In addition to size detection, sensors can also perform weight detection in the sorting system. The weight of each item is different, and sensors can detect the weight information of the item, compare it according to preset standards, and achieve classification and sorting of the items.
The role of sensors in barcode recognition
Sensors can also be used for barcode recognition. When the items attached to barcode labels flow through the sorting system, sensors can recognize the information on the barcode, classify and sort the items to the corresponding areas, improving the efficiency and accuracy of item sorting.
Sensors are an indispensable component of sorting systems, achieving automation and efficiency in sorting through functions such as item detection, size measurement, weight detection, and barcode recognition. I believe that with the continuous progress of technology, the important role of sensors in sorting systems will become more prominent.
