Design and Simulation of Environment Indoor Air Quality Monitoring and Controlling System using IoT Technology

Environment indoor quality (EIQ) is a multifaceted problem encompassing a broad range and fluctuation of contaminants that pose risks to human health, satisfaction, welfare, and efficiency, particularly in relation to environment indoor air quality (EIAQ). The presence of indoor air pollutants (IAP) in the environment significantly influences the decline in the quality of human life, owing to the hazards associated with indoor air pollution and discomfort-causing pollutants affecting thermal comfort. This research features a proposed EIAQ monitoring and controlling system based on the environment indoor air quality index (EIAQI) for detecting, identifying, assessing, and controlling air pollutants. Further, it monitors the concentration of the gases and calculate the toxicity level of the environment status index. It also provides the output control system such as ventilation system and alert system to mitigate the air pollutants based on EIAQI automatically. The EIAQ system integrated with IoT technology to provide a monitoring application the entire air pollutant and EIAQI. As a result, the use of the indoor air quality (IAQ) system becomes a suitable method for identifying, categorizing, assessing, offering guidance, and implementing preventive measures to enhance the quality of the environment.
