IoT Based Smart Wearable for Air Quality Monitoring

Internet of Things has been providential in tackling a lot of problems that amassed a lot of attention and concern among people. A lot of consumer electronics today have multiple IoT subsystems functioning in them, that not only make a product smart, but also increases its value as a product. Air pollution is a very serious problem, that has proved its deleteriousness over the past few years. With a lot of densely populated cities, now branded as unsafe for people to live in, due mainly to the polluted air it is home to, the importance for a solution that alerts city dwellers about the air quality of a space is gaining momentum. IoT, however could solve this problem, by educating people about the air quality, after measuring them. A dedicated air pollution monitoring device will not be effective enough in making people accept that an air quality monitor is a necessity and not a luxury. Therefore, this work integrates an air pollution monitoring system into a wearable like a watch that also doubles as a fitness tracker and a temperature monitor. Air pollutant levels, footsteps taken and ambient temperature are all sensed and displayed by the smart watch proposed in this work and is also casted to a custom designed smartphone application. The device proposed is novel in what it can do at the extremely low cost that it takes for its build. Thus a watch that can do everything that other watches can and cannot do has been proposed, with a tight integration to a smartphone app.
