Non‑Intrusive Diagnostics for Modern Firearms
The Weapon Health Monitor v0.1 is a compact, external telemetry module designed to bring real‑time diagnostics, maintenance forecasting, and environmental awareness to small arms without modifying internal components or affecting reliability.
Built for field technicians, training programs, security organizations, and data‑driven armories, the module transforms a traditionally analog tool into a measurable platform.
Core Capabilities
• Shot Detection via Sensor Fusion
A built‑in IMU captures vibration and rotational signatures while a thermal sensor monitors heat cycles. Combined, they produce a highly accurate firing‑event classifier without interacting with the firearm’s internal mechanics.
• Environmental Exposure Logging
Temperature, humidity, and shock events are continuously recorded, creating a historical profile of wear conditions and corrosion risk.
• Predictive Maintenance Index
Using a weighted model of firing cycles, heat stress, and exposure conditions, the system calculates a live MaintenanceScore—a simple, readable indicator of equipment health.
• Modular Mounting Architecture
Attaches externally via Picatinny or M‑LOK clamps. No gunsmithing. No permanent changes.
• Data Export for Analysis
All telemetry is logged in standard CSV format and can be fed into:
- dashboards
- training analysis suites
- armory management tools
- custom analytics pipelines
Technical Overview
- IMU: 6‑axis accelerometer/gyroscope
- Environment Suite: temperature + humidity
- Processor: microcontroller or SBC (ESP32 / Raspberry Pi Zero)
- Power: rechargeable cell
- Data Output: USB‑C or wireless (optional prototypes)
- Enclosure: polymer, weather‑resistant, low‑profile design
Why It Matters
Firearms lack the diagnostic infrastructure that every modern machine—from drones to cars—relies on. Maintenance remains manual, reactive, and guess‑based.
The Weapon Health Monitor introduces:
- quantified wear
- clearer maintenance cycles
- actionable training feedback
- fleet‑level operational insight
It’s a step toward a future where armories operate with the same clarity as digital systems: measurable, trackable, predictable.
Prototype Status
The v0.1 prototype includes:
- fully functional sensor fusion
- firing‑event classification
- environmental logging
- maintenance scoring algorithm
- CSV export and terminal visualization
Next iterations will focus on:
- on-device LED indicators
- encrypted wireless sync
- cloud dashboards
- expanded sensor suite
