Ragnar Rusense - Camera Free Surviellence Network

Want to be included in our credits?
Pierre Gode just shipped something your security cameras can't compete with.

RuSense turns any standard 2.4 GHz WiFi signal into a no-camera surveillance
system that detects motion, presence, people count, and resting vital signs —
THROUGH WALLS — with zero lenses pointed at anyone. No images. No blindspots.
Works in complete darkness.

This is the full RuSense deep-dive inside the Ragnar project — the open-source
Raspberry Pi security platform that's already the most capable e-Paper HAT build
in the maker space. RuSense adds a completely new dimension: ESP32-S3 or C6 nodes
read WiFi Channel State Information (CSI), detecting how a moving body distorts
radio waves, and report live data straight into the Ragnar web dashboard. With a
trained model, it even detects coarse pose estimation and vital signs like
breathing rate and heart rate. Camera-free. Privacy-first. Open source.

✅ WHAT WE COVER:
• How WiFi CSI presence sensing actually works
• Flashing your ESP32 node straight from the browser — zero toolchain needed
• Installing the RuSense sensing backend (ragnar-sensing.service)
• Security Mode vs Health Mode — and when to run each
• Running the calibration wizard for accurate detection
• Building a multi-node offline mesh
• Live presence + motion data in the Ragnar dashboard

⚙️ HARDWARE USED:
• Raspberry Pi Zero 2W / Pi 4 / Pi 5
• ESP32-S3 or ESP32-C6 sensor node
• 2.13" e-Paper HAT (optional, for display mode)
