WiFi-Mat v3.2 - AI Thermal Monitor + WiFi CSI Sensing
======================================================
Embedded AI system combining thermal monitoring with WiFi-based
presence detection, inspired by WiFi-DensePose technology.
For Heltec ESP32-S3 with OLED Display
CORE CAPABILITIES:
------------------
* Thermal Pattern Learning - Spiking Neural Network (LIF neurons)
* WiFi CSI Sensing - Through-wall motion/presence detection
* Breathing Detection - Respiratory rate from WiFi phase
* Anomaly Detection - Ruvector-inspired attention weights
* HNSW Indexing - Fast O(log n) pattern matching
* Power Optimization - Adaptive sleep modes
VISUAL INDICATORS:
------------------
* Animated motion figure when movement detected
* Radar sweep with detection blips
* Breathing wave visualization with BPM
* Status bar: WiFi/Motion/Alert icons
* Screen flash on anomaly or motion alerts
* Dynamic confidence bars
DISPLAY MODES (cycle with double-tap):
--------------------------------------
1. STATS - Temperature, zone, patterns, attention level
2. GRAPH - Temperature history graph (40 samples)
3. PTRNS - Learned pattern list with scores
4. ANOM - Anomaly detection with trajectory view
5. AI - Power optimization metrics
6. CSI - WiFi CSI motion sensing with radar
7. RF - RF device presence detection
8. INFO - Device info, uptime, memory
AI POWER OPTIMIZATION (AI mode):
--------------------------------
* Mode: ACTIVE/LIGHT/DEEP sleep states
* Energy: Estimated power savings (0-95%)
* Neurons: Active vs idle neuron ratio
* HNSW: Hierarchical search efficiency
* Spikes: Neural spike efficiency
* Attn: Pattern attention weights
WIFI CSI SENSING (CSI mode):
----------------------------
Uses WiFi Channel State Information for through-wall sensing:
* MOTION/STILL - Real-time motion detection
* Radar Animation - Sweep with confidence blips
* Breathing Wave - Sine wave + BPM when detected
* Confidence % - Detection confidence level
* Detection Count - Cumulative motion events
* Variance Metrics - Signal variance analysis
Technology based on WiFi-DensePose concepts:
- Phase unwrapping for movement detection
- Amplitude variance for presence sensing
- Frequency analysis for breathing rate
- No cameras needed - works through walls
BUTTON CONTROLS:
----------------
* TAP (quick) - Learn current thermal pattern
* DOUBLE-TAP - Cycle display mode
* HOLD 1 second - Pause/Resume monitoring
* HOLD 2 seconds - Reset all learned patterns
* HOLD 3+ seconds - Show device info
