The Air Quality Smart Monitoring and Management System

Abstract

In this project, the problem that I attempt to solve is the lack of knowledge and action surrounding poor air quality. Inspired by a trip to India, I took action and built a prototype device that gave auditory and visual indications of the air quality and turned an air ionizer as necessary. During project development, I interfaced a microcontroller with multiple peripheral devices, and I studied associated documentation as necessary. Using this knowledge, I wired each component to a digital or analog pin, and a ground power connection. Some components also required a 5 voltage connection. I then programmed my microcontroller to read the temperature, humidity, and pollutant ppm values from the associated sensors. During project development, I tested my device in five environments: my room, my backyard, an open garage with a car running, the air after a car runs, and a car running in a closed garage. I used this data to determine what pollutant ppm values constitute good, poor, and bad air quality. Using this information, I programmed the microcontroller to use LEDs and a buzzer to notify users of the current air quality conditions. Finally, I later incorporated an ionizer into the project, and programmed the system to switch it on when the air quality is bad. Through further testing, I determined that each component did its job, allowing me to validate. Thus, this device could make a difference for people in industrial countries facing respiratory diseases and can be applied to various fields of science.
