Health Sense
AQI Hat
Christopher Vidaurrazaga and Hunter Stillwell
Project Brief
The AQI Hat is a wearable device that can let the user know about the air quality around them and how healthy it is to have continued exposure to that air. People get lots of diseases from bad air pollution and it is good to have a product that can help people know more about their health and keep them healthier in the long run.
This hat is made for an individual user that will be able to wear the hat in their daily lives and let them know where there is bad air pollution. The user can also learn where there is bad air pollution in their lives and try to change it by either changing air filters or even just opening a window. The hat has two sensors, a temperature and humidity sensor and a MOX gas sensor. The gas sensor needs the temperature and humidity sensor to be able to detect the air pollution. The gas sensor detects VOCs (volatile organic compounds) and then the hat maps out the value to a color gradient to show different colors for different air qualities. The colors range from green (healthy) to purple (hazardous).

AQI Hat is a wearable air quality monitor designed to increase awareness of air pollution, a public health threat that causes the premature deaths of around seven million people worldwide. Inspired by other successful air pollution awareness campaigns, this project aims to create systemic change through widespread public awareness and data collection.
This project could be used by anyone interested in air pollution or citizen science but would be particularly helpful to users in areas particularly affected by air pollution. By combining air quality sensors with a NeoPixel strip and wearable light diffusor, this project will alert the wearer and surrounding observers of the potential health risks of the air they are breathing. These sensors would also record air quality data in various environments. This data could be used to study air quality around the world.
