Problem
Traditional air quality monitoring relies on distant sensors or static readings, failing to capture the hyper-local and dynamic nature of personal air exposure. This lack of real-time, granular data prevents individuals from understanding how their immediate environment impacts their health, cognitive function, and overall well-being.
Solution
Halo Air provides a compact, smartphone-attachable environmental sensor that delivers real-time, hyper-local air quality data. The device measures key pollutants including carbon dioxide (CO₂), particulate matter (PM₁.₀, PM₂.₅, PM₁₀), and total volatile organic compounds (TVOCs), alongside temperature and humidity. By integrating with a companion mobile application, Halo Air offers users actionable insights and customizable alerts, empowering them to make informed decisions about their immediate surroundings. This enables proactive adjustments to ventilation, filtration, or environmental exposure to optimize personal health and cognitive performance.
Target Audience
Primary users include health-conscious individuals, biohackers, remote workers, parents concerned about indoor environments, and anyone seeking to optimize their personal space for improved cognitive function and well-being.
Features
- **Multi-pollutant Sensing:** Utilizes NDIR sensors for accurate CO₂ measurement (400-5000+ ppm range) and laser-based optical sensors for precise detection of PM₁.₀, PM₂.₅, and PM₁₀ particulates (0-500 µg/m³ range).
- **Chemical Compound Detection:** Integrated sensor for total volatile organic compounds (TVOCs) to monitor airborne chemical concentrations.
- **Environmental Parameters:** Onboard sensors for ambient temperature (°C/°F) and relative humidity (%).
- **Smartphone Integration:** Attaches magnetically via MagSafe (iPhone) or adhesive magnet (Android) for continuous monitoring.
- **Real-time Data Visualization:** Companion mobile application displays live readings, historical trends, and environmental data.
- **Customizable Alerts:** User-defined thresholds trigger notifications on the smartphone when specific pollutant levels are exceeded.
- **Lock Screen Widget:** Provides at-a-glance air quality status directly from the phone's lock screen.
- **Actionable Recommendations:** App provides context-sensitive guidance for improving air quality based on detected pollutants.
- **Portable and Discreet Design:** Compact and lightweight form factor ensures minimal impact on phone usability.
