This solution utilizes the NuMicro^® M55M1 microcontroller to upgrade traditional fans into smart appliances equipped with "active perception." By executing high-performance object detection at the Endpoint AI, we achieve a fully offline, low-latency, and privacy-secure contactless control system. Replacing physical buttons with intuitive gesture interactions, users can signal "OK" to adjust speed, "Rock" for smart shutdown, or "Scissors" to activate wide-angle oscillation. The highlight is the "Smart Tracking Mode“, where the system instantly locks onto the user's coordinates and drives the motors to follow them. This is not just a fan; it is the ultimate demonstration of MCU integration combining visual AI and precision motor control.
