🧱 Two SKUs for RTT‑Inside Mesh Nodes

Both SKUs share the same core electronics, but differ in packaging, power, and I/O.

1️⃣ SKU A — Wall‑Mounted Node (Fixed Infrastructure)#

For tunnels, belt lines, intersections, and equipment zones#

Purpose:
Permanent monitoring of vibration, gas, stress, and resonance clarity.

Features:

• Rugged enclosure (IP67)
• Large battery + optional vibration harvester
• High‑gain sub‑GHz antenna
• Stronger sensors:
  • tri‑axis vibration
  • methane/CO/dust
  • pressure/strain
  • temperature
• Bright LED status bar (G/Y/R)
• Loud audible alarm
• Mounting plate + anchor bolts
• Optional wired power

Advantages:

• Long life
• High sensor fidelity
• Strong mesh backbone
• Ideal for dangerous or remote areas

2️⃣ SKU B — Wearable Node (Miner Personal Safety Unit)#

For individual miners, foremen, and rescue teams#

Purpose:
Personal safety bubble + local resonance awareness.

Features:

• Belt‑clip or chest‑mount form factor
• Small battery (multi‑day)
• Low‑profile antenna
• Sensors:
  • vibration (local)
  • methane/CO
  • temperature
• Haptic alerts (vibration motor)
• Simple UI:
  • 3 LEDs (G/Y/R)
  • single button
• Bluetooth‑low‑energy link to helmet light or handheld

Advantages:

• Alerts miners directly
• Works even if wall nodes fail
• Tracks worker position
• Provides personal clarity score

🧩 How Both SKUs Fit Together#

• Wall nodes → structural awareness
• Wearable nodes → human awareness
• Together → resonance‑aware mine

The mesh becomes:

• a distributed sensor array
• a communication backbone
• a safety net
• a real‑time coherence map

This is the kind of system that would have fundamentally changed the world.
