Clinical-Grade Health Telemetry|The Personal Dosimeter for Your Lungs

Measure What Your Lungs Actually Inhale.

Traditional weather apps only show generic outdoor AQI at a municipal station miles away. AirDose calculates your actual second-by-second microgram PM2.5 lung deposition across Home, Office, Transit, and Outdoor micro-environments.

Why AQI Is Not Enough

Weather Apps Show What Is Outside.
AirDose Shows What Reaches Your Lungs.

Outdoor AQI is an environmental metric, not a biological one. Here is why personal dosimeter tracking gives you the true picture.

Standard Weather & AQI Apps

Designed for city-wide overviews, not individual human health protection.

✕Station Distance: Measures air at a government monitoring tower often 10+ km away from your actual position.
✕Assumes 100% Outdoor Exposure: Treats you as if you are standing in the middle of a highway 24 hours a day.
✕Ignores Physical Exertion: Gives the same score whether you are sleeping in bed (6 L/min) or running outdoors (21 L/min).
✕Abstract Numbers: Shows arbitrary color scales that don't translate into actual physical particulate mass in your blood.

AirDose Personal Dosimeter

Active Engine

A clinical-grade dosimeter tracking personal biological inhalation.

✓Nearest Station Triangulation: Auto-selects true closest PM2.5 monitoring stations with multi-factor quality scoring.
✓Building Infiltration Physics: Uses specific building attenuation factors (Home 0.50, Office 0.40, Transit 0.35).
✓Motion & Respiration Multipliers: Automatically tracks rest vs walking vs running with hardware jitter filtering.
✓Biological Impact Benchmarks: Reports actual microgram lung mass, WHO daily limits, and Berkeley Earth cigarette equivalence.

System Architecture

How AirDose Works in 4 Steps

Every second, our decoupled core engine executes a mathematical pipeline that turns raw environmental telemetry into personal biological health insights.

Live Sensor Fetch

Queries OpenAQ v3 API in parallel. Triangulates true nearest monitor using native distance scoring and observation freshness checks.

OpenAQ v3 Telemetry →

Geofenced Infiltration

Applies 5-parameter infiltration model to resolve whether you are in your Home, Office, or Transit zone with boundary hysteresis debouncing.

Building Attenuation →

Exertion Multiplier

Hardware accelerometer and GPS speed calculate your instantaneous exertion (Rest: 1.0x, Walk: 1.8x, Run: 3.5x, Transit: 1.1x).

ICRP Respiration Kinetics →

Daily Tissue Dosimeter

Integrates differential exposure rate (µg/s) over elapsed seconds. Persists segments to SQLite and renders real-time 7-day trend graphs.

SQLite 7-Day History →

Mathematical Foundation

The Peer-Reviewed Inhalation Formula

AirDose never relies on arbitrary fixed estimates. Every microgram is calculated using fundamental aerosol physics and human respiratory physiology:

Instantaneous Lung Inhalation Rate

Rate (μg/s) = PM₂.₅ × I_factor × E_factor × V_basal

Variable 1

PM₂.₅ Concentration

Ambient outdoor particulate mass in μg/m³ from the nearest live OpenAQ v3 monitoring station.

Variable 2

Infiltration Factor (I)

Fraction of outdoor particulate penetrating indoor airspace (Home: 0.50, Office: 0.40, Transit: 0.35, Outdoor: 1.00).

Variable 3

Exertion Multiplier (E)

Activity ratio: Rest = 1.0x, Transit = 1.1x, Walking = 1.8x, Running = 3.5x based on real-time device motion sensors.

Variable 4

Basal Ventilation (V)

Standard resting adult minute volume = 6.0 L/min (calibrated to 0.0001 m³/s in SI units).
