AURA - Air & UV Real-time Alerts

Aura is a portable device developed at CNM’s IoT Bootcamp that monitors:

UV exposure, air quality (PM10), humidity and temperature in real time to help users make healthier, more informed decisions about their environment.

As someone passionate about health, technology, and the outdoors, I wanted to create a solution for people—especially those who hike, bike, or work outside—who are constantly exposed to changing environmental conditions. Knowing when air quality reaches dangerous levels or UV radiation spikes can help prevent long-term health issues like respiratory problems or skin damage.

Aura uses a combination of sensors:

* UV Intensity Sensor Detection Ultraviolet: Detect exposure to harmful rays.

*Laser PM2.5 Sensor (HM3301) : Monitoring air pollution PM10.

*BME 280: Temperature and Humidity tracking.

*MP3 player and Speaker: Audio alerts.

It features real-time feedback through audio alerts via DFPlayer for dangerous conditions. All components are embedded in a compact, wearable enclosure, making it ideal for daily use.

Developed and tested AURA at CNM’s Fuse Makerspace, where I learned to prototype with microcontrollers, connect sensors, and bring ideas to life.
