Abstract
FDMS‑2.0 is an open‑hardware, FPGA+ARM‑based environmental observatory capable of simultaneously measuring eight physics domains:
-
Thermal
-
Acoustic
-
Infrared
-
Vibration
-
Optical spectral
-
Airflow
-
Electromagnetic field
-
Low‑frequency EM antenna
All domains are sampled in parallel, timestamped at microsecond resolution, and fused into a unified environmental frame. FDMS‑2.0 establishes a baseline environmental model, computes an Environmental Stability Index (ESI), and detects anomalies only when multiple physics domains deviate simultaneously, eliminating false positives.
FDMS‑2.0 is fully buildable using off‑the‑shelf components, reproducible wiring, open firmware, and compact ASCII diagrams. It integrates optionally with other Caldwell research inventions (CMHRE‑Ω1.0, CUDRE‑1.0, VETI‑4.0, MMRA‑2.0, ONRS‑2.0, VMR Titan‑2.0, CNG‑Loop, URES‑2.0) but does not depend on them.
This research disclosure provides complete architecture, BOM, wiring, firmware requirements, calibration, controlled experiments, field experiments, pass/fail criteria, data formats, mesh networking, triangulation algorithms, builder instructions, and open‑hardware declarations required for prototype construction and scientific testing.
TECHNICAL FIELD
Environmental sensing, multi‑domain measurement, FPGA parallel sampling, ARM fusion, anomaly detection, baseline learning, mesh networking, environmental mapping, open‑hardware scientific instrumentation.
BACKGROUND
Environmental events rarely manifest in a single physical domain.
Examples:
-
Ignition produces thermal rise, acoustic agitation, airflow collapse, and EM drift.
-
Structural fatigue produces vibration harmonics, acoustic signatures, and thermal stress.
-
HVAC instability produces airflow turbulence, thermal imbalance, and acoustic changes.
-
Electrical drift produces EM field anomalies, vibration changes, and thermal rise.
Traditional sensors measure one domain at a time.
FDMS‑2.0 measures eight domains simultaneously, synchronized to microseconds.
