Experimental Verification of Automatic Sorting Machine Using Infrared Proximity Sensor and Microcontroller

This article proposes the design and builds of an automatic marigold (economic crop) sorting machine by sorting sizing 5 sizes with working together between conveyor belts, electric motors, and microcontroller control unit. The system designed to connect to WIFI to store data on Cloud computing and can display the information through the screen in Real-Time in numeric data format and graphs, Test the accuracy of the system by comparing experiments between microcontroller control unit and PLC control unit, which sold in the market at a high prices but this designed system has a low price and equivalent performance. The results from repeated tests showed that the automatic marigold sorting machine can operate as specified according to the design by separating the size of the marigolds.
