The automatic sorting system has been reported to be complex. Programmable logic controller used for the operation and the control of an industrial unnamed system, namely conveyor, pneumatic cylinders, solenoids. Thus, we have developed a system for sorting object with any metallic impurities using sensor and motor controlled by Programmable Logic Controller (PLC) and the conveyor in the system passes the object through sensors and hence sorting logic is decided. The research obtained shows that metals and red colors wood were sorted into their respective and correct position. The system can be implemented by choosing the desire colors which depend on the setup of the color sensor.
