This team is developing a smart indoor air-purifying system called the Aeolian Air Butler. The system consists of sets of sensors that send indoor air pollution data to the user’s phone and allows the user to remotely control the air purifier. The system can also provide the user with a comparison of air quality at nearby places (malls, cinemas, shops, restaurants) and air quality distribution inside public architectures, allowing people to make their outing plans based on real-time air quality ratings.
