Air Quality Arduino Based Monitoring System

Air quality is a very important health factor. However, there are situations where humans are exposed to poisonous air that has a high concentration of Volatile Organic compounds (VOC), especially indoor environments such as car cabins and offices. It is important for a better health to breathe clean air that has low concentrations of VOC. This paper presents a design for a system that aims to notify the residents of VOC's concentration level in both indoor and outdoor environments. The system is Arduino-based, it will monitor and detect total volatile organic compounds (TVOC) and then inform the user via wireless communication system of its levels to take actions.
