μMotionPython

μMotion is a lightweight motion detection library for Python inspired by the Arduino μMotion library.
It uses OpenCV and NumPy to detect motion on any camera compatible with OpenCV.

Features

• Motion detection in Python for Raspberry Pi, Jetson, PC, etc.
• Two modes:
  • SUMMARY Mode – Counts total pixels that changed between frames
  • RAW_DIFF Mode – Prints ASCII per-pixel difference (. for changed, space for unchanged)
• Adjustable threshold for motion sensitivity
• Simple and clean API similar to Arduino library
• Easy to run examples for quick testing

How μMotion is Different from OpenCV Motion Detection

OpenCV is a general-purpose computer vision library. μMotion is a motion intelligence engine purpose-built for embedded vision, real-time performance, and AI-assisted decision systems. Built for the edge. Faster than OpenCV.
