Abstract

SCADA or Supervisory Control And Data Acquisition is a system that allows companies to monitor and control industrial processes locally or at remote locations, gather and process real-time data, interact with devices such as sensors, valves, pumps, and motors through a human-machine interface (HMI) software, and record events into a log file. This project demonstrates a wireless SCADA system using a Raspberry Pi 3 Model B as the main unit which communicates with a Remote Terminal Unit (RTU) controlled by Arduino Nano. The graphical user interface (GUI) for central monitoring and control is hosted in the main unit while the RTU is equipped with sensors and actuators. The results indicate that the communication between the main and remote terminal units is a significant and potentially troublesome aspect of the system which must be carefully designed considering ease-of-use, latency, reliability, efficiency, and security. The study concluded that a Raspberry Pi 3 is a viable solution for implementing a wireless SCADA system together with microcontrollers and suitable communication modules.
