Optic Flow PMW3901 (SPI)

File:TArduinoPMW3901.png

Summary

The Optic Flow PMW3901 component provides motion detection and tracking using optical flow technology. It communicates using the SPI interface and outputs movement data and image information.

Description

The PMW3901 is a low-power optical flow sensor that enables precise motion detection by tracking surface patterns. It uses image correlation to detect movement in both X and Y directions with high accuracy. The sensor operates through SPI interface and provides real-time motion data suitable for applications such as drone navigation, robotic positioning, gesture recognition, and any system requiring relative motion tracking without external references.
