AUTOMATED MIXING PROCESS SYSTEM BY USING PROGRAMMABLE LOGIC CONTROLLER AND ARDUINO UNO

Abstract

The Fourth Industrial Revolution is a rapidly growing technology convergence that encompasses the physical, digital, and biological domains. It is expected to increase productivity by 30% across industries by 2030. Automation, the use of machines to perform tasks without human intervention, is a key aspect of this revolution. PLCs (programmable logic controllers) and Arduino microcontrollers are widely used in automation. However, there are challenges in achieving accurate liquid mixing in industries using manual methods. Automation systems can improve efficiency, accuracy, and safety while reducing costs and human errors. Testing and verification of a prototype automated mixing system have been conducted, including communication between Arduino and PLC, mechanical and electrical testing, and PID tuning. Limitations include cost constraints, sensor accuracy, and communication difficulties. Recommendations include seeking cost-effective alternatives, calibrating, or replacing sensors, and exploring advanced communication methods.
