RuView GitHub Complete Guide
Navigate the RuView GitHub repository: structure, install, and contribution roadmap.
The RuView GitHub repository is the canonical home for our firmware, python preprocessing bridges, pre-trained AI weights, and documentation. Navigating the repository is straightforward once you understand its modular layout. This guide will walk you through cloning the codebase, installing system dependencies, and compiling the active examples to run your first passive radar within minutes.
Navigating the Directory Structure
The repository is divided into four main directories: `/firmware` (housing C/C++ ESP-IDF source files), `/core` (the Python preprocessing and filtering bridge), `/models` (our CNN-LSTM neural weights), and `/dashboard` (the React-based spatial Web interface). Always start by reading the root `README.md` for absolute setup baseline dependencies.

Electromagnetic Wave Propagation & CSI Physics
To fully grasp how wireless sensing works, we must investigate the mathematical principles of modern radio frequency (RF) propagation. Traditional signals like RSSI only provide the average overall power of a received wireless packet. Conversely, Channel State Information (CSI) extracts complex vectors mapping individual Orthogonal Frequency-Division Multiplexing (OFDM) subcarrier channels. In a standard 20 MHz or 40 MHz WiFi spectrum, the signal is split into 56 to 114 separate subcarrier channels. For each subcarrier, the CSI packet header records the exact Amplitude (signal attenuation) and Phase (fractional cycle shift).
Human bodies are comprised of more than 60% water, making them highly conductive dielectric objects in the path of 2.4 GHz and 5.8 GHz frequencies. As waves travel between the transmitter and receiver, they bounce off walls, obstacles, and humans in a phenomenon known as Multipath Propagation. The physical displacement of a human body perturbs this multipath beam network, creating constructive and destructive interference waves. For a comprehensive overview of how these physical shifts are visualized in real-time, try our Interactive 3D WiFi Radar Demo.
Selecting and Configuring ESP32 Microcontrollers
Implementing a spatial WiFi radar does not require industrial SDR (Software Defined Radio) equipment. The RuView project operates entirely on standard, inexpensive microcontrollers. For high-fidelity telemetry, we highly recommend the ESP32-S3 DevKit. The S3 series features dual XTensa LX7 cores with custom vector instruction extensions that provide hardware acceleration for raw signal matrices.
A typical DIY radar setup consists of a transmitter (Tx) emitting beacon packets and a receiver (Rx) listening on the same WiFi channel. During selection, look for boards featuring an external IPEX antenna connector instead of a standard PCB trace antenna, as high-gain external antennas heavily minimize noise. For a full list of certified microcontrollers and specific command line flashing commands, read our extensive ESP32 WiFi Radar Guide.

Privacy Preserving Spatial Sensing & Surveillance Alternatives
As ambient computing spreads, security systems raise massive privacy concerns. Cameras record actual visual images, creating permanent files that are vulnerable to hacks. Passive WiFi sensing is **100% privacy-preserving**. It captures no optical features, faces, or bodies — only numeric signal amplitude vectors.
The data is entirely ephemeral: processed locally and instantly discarded. It is impossible to reconstruct a face from a CSI matrix. This makes WiFi sensing ideal for bedrooms, bathrooms, and private offices. For a comprehensive introduction to camera-free spatial computing, explore our starter overview What is RuView?

FAQ
How is RuView GitHub Complete Guide implemented practically?
Implementing this practically involves deploying inexpensive ESP32 microcontrollers, flashing standard CSI firmware, and routing the Base64 serial streams to a local edge processor running the RuView AI model array.
Does this setup interfere with my home WiFi?
No. The system uses standard IEEE 802.11 beacons and passive sniffing modes, operating seamlessly in the background without affecting your network speed or causing interference.
