# WiFi CSI Sensing Use Cases Overview

> Explore all Wavey use cases: occupancy detection, motion and activity recognition, presence sensing, elder care, security, smart home, and analytics.

Wavey is an open-source WiFi CSI sensing stack that turns commodity access points into distributed sensors. This page maps every supported use case to the detection task it solves, so you can pick the scenario that matches your deployment. Start with the detection ladder to see which tasks are feasible, then choose the scenario below.

## Occupancy and Presence

<CardGroup cols={2}>
  <Card title="Occupancy Detection" icon="users" href="/use-cases/occupancy-detection">
    Binary occupancy from WiFi CSI change-point detection on an empty-room baseline — why it tolerates noise, how it differs from MAC counting, and HVAC control semantics.
  </Card>

  <Card title="Presence & Breathing" icon="lungs" href="/use-cases/presence-detection">
    Micro-Doppler presence sensing from WiFi CSI — respiration band physics, SNR requirements, still-person detection, and why PIR cannot see periodic chest motion.
  </Card>

  <Card title="Occupancy Analytics" icon="chart-bar" href="/use-cases/occupancy-analytics">
    Anonymous occupancy analytics from WiFi CSI — temporal aggregation, utilization metrics, zone heatmaps, GDPR-safe sensing vs MAC tracking, and honest headcount limits.
  </Card>

## Motion, Safety, and Automation

<CardGroup cols={2}>
  <Card title="Motion & Activity" icon="person-running" href="/use-cases/motion-activity-detection">
    Human activity recognition on WiFi CSI — CSI-speed modeling, dual-stream transformers, spectrogram classifiers, and cross-site transfer.
  </Card>

  <Card title="Elder-Care Monitoring" icon="heart-pulse" href="/use-cases/elder-care-monitoring">
    Ambient elder-care sensing with WiFi CSI — anomaly-based fall detection, inactivity monitoring, online adaptation, and non-medical boundaries.
  </Card>

  <Card title="Security & Intrusion" icon="shield-halved" href="/use-cases/security-intrusion-detection">
    Zone-level intrusion detection with WiFi CSI — NLOS motion through drywall, darkness-invariant sensing, device-free vs MAC tracking, and what you learn vs what you cannot.
  </Card>

  <Card title="Smart-Home Automation" icon="house-signal" href="/use-cases/smart-home-automation">
    WiFi presence sensing for home automation — presence-hold vs motion-pulse events, debouncing, hysteresis, and why occupancy beats PIR for HVAC and lighting scenes.
