 **See through walls with WiFi.** No cameras. No wearables. Just radio waves.
 
-WiFi DensePose turns commodity WiFi signals into real-time human pose estimation, vital sign monitoring, and presence detection — all without a single pixel of video. By analyzing Channel State Information (CSI) disturbances caused by human movement, the system reconstructs body position, breathing rate, and heartbeat using physics-based signal processing and machine learning. The [server](#-quick-start) is optional for visualization and aggregation — the [ESP32 runs edge intelligence independently](#esp32-s3-hardware-pipeline), performing on-device presence detection, vital signs, and fall detection without any host connection.
