| Abstract | This paper presents the design and implementation of an Arduino–Python platform for near real-time multi-channel signal acquisition systems, demonstrated through a three-phase electrical measurement application. The proposed platform integrates an analog signal conditioning board, an Arduino MEGA board for analog-to-digital conversion (ADC), and a PC-based Python application for continuous serial data acquisition and processing, visualization, and storage. Communication between the board and the host computer is established via USB serial interface, enabling continuous acquisition and monitoring of six channels (three voltages and three currents). The capabilities of the platform are evaluated experimentally in a laboratory setup involving a three-phase induction motor. A cohesive data processing pipeline that facilitates the seamless transition from hardware acquisition to Python-based analysis is proposed. The results demonstrate the applicability of the developed platform for laboratory-scale three-phase monitoring and signal analysis. |
