Abstract

This paper presents the design, development, and experimental validation of an intelligent, cost-effective, and Internet of Things (IoT)-enabled Variable Frequency Drive (VFD) control framework for three-phase induction motors. Utilizing a high-performance PIC18F25K22 microcontroller as the localized processing engine, the system achieves granular speed modulation by driving a Lenze AC Tech SMVector VFD via a highly precise 0-10V analog reference signal. This reference voltage was generated using an external MCP4922 12-bit Digital-to-Analog Converter (DAC) operating over the Serial Peripheral Interface (SPI) protocol, minimizing the CPU overhead and eliminating analog calibration drifts. Real-time ambient environmental tracking was achieved using a calibrated SHT40I sensor array, providing automated, threshold-triggered speed scaling to safeguard electrical enclosures from thermal stress. Operational telemetry, encompassing motor state, temperature, humidity, and drive duty cycles, is serialized over a Universal Asynchronous Receiver-Transmitter (UART) interface, establishing seamless integration with edge devices, virtual COM ports, and cloud platforms via Node-RED dashboards. The experimental findings demonstrate a maximum DAC absolute voltage error within ± 0.2% and highly stable data-logging capabilities. The proposed framework provides a robust, scalable, and low-cost decentralized alternative to conventional PLC-SCADA architectures, in alignment with modern Industry 4.0 paradigms.

Keywords—Variable Frequency Drive (VFD), Three-Phase Induction Motor, PIC18F25K22, MCP4922, IoT Telemetry, Industrial Automation, Smart Enclosures.
