Real-time air quality monitoring system in residentials using Arduino Uno wi-fi / Aqil Najmi Anuar

In recent times, the significance of air quality surrounding residential areas has been declining rapidly, which in turn may cause severe long-term effects to residential’s health. If said problem is not adequately addressed, uninformed residents may be subjected to coughing or itchy eyes that may cause or worsen a variety of lung and respiratory illnesses, which can result in hospitalizations, cancer, or even premature death. With this inspiration, this thesis presents an air quality monitoring system by using an Arduino Uno Wi-fi as a microcontroller, the system detects the air pollutants in the air and converts it into units of Part Per Million which can be used to evaluate the conditions of the air quality in the surroundings. Readings from the sensors will then be sent to an online application, Blynk, to view air quality conditions. Thus, it is essential to keep track of the air quality by referring to Malaysia’s air quality index especially in residential areas as the air quality can heavily impact a person’s health. Environmental data monitoring is beneficial for many purposes. However, accessibility of the monitored data could be challenging due to factors such as time, cost, and energy
