Sensing Lungs is an interactive project exploring how urban ozone exposure affects the body, using wearable “breathing” sensors shaped like lungs. Developed to study disparities across Harlem and Columbia’s campus, it collected heart rate and ozone data. Initial findings suggested ozone influenced heart rate, but deeper analysis revealed movement and location as the true drivers. The project critiques oversimplified environmental-health links and proposes improved, community-based sensing for future research.
