**WiFi CSI radar for Flipper Zero + ESP32** Detect motion, presence, and proximity through walls using WiFi Channel State Information — no cameras, no IR, no special sensors.

Teach three $10 ESP32-S3 boards to recognise what you're doing from WiFi alone, with your webcam as the teacher

Applications based on Wi-Fi CSI (Channel state information), such as indoor positioning, human detection

Detect motion, presence and breathing through walls with ordinary WiFi. ESP32-S3 captures 802.11 CSI, a Raspberry Pi 4 runs the DSP, a browser dashboard shows it live.

Wi-Fi Vision: Device-free human pose estimation and activity recognition using ESP32 CSI and machine learning.

Radar V2.0 is a high-performance Wi-Fi CSI (Channel State Information) sensing and security system built for the M5Stack Cardputer and Cardputer ADV (ESP32-S3). By analyzing multipath radio-wave reflections and Fresnel zone distortions across 16 to 32 OFDM subcarriers, it detects motion, breathing, and spatial presence inside rooms and through wall

The open-source wireless research platform for ESP32.

π RuView turns commodity WiFi signals into real-time spatial intelligence, vital sign monitoring, and presence detection — all without a single pixel of video.
