Automated Ventilation System for Maintaining indoor CO2 Concentration to Reduce Allergic and Respiratory Diseases: for Rural Area in Batticaloa, Sri Lanka

Ventilation is essential to expel indoor generated pollutants from indoor air or weaken their focus to satisfactory levels. CO2 and bio-effluents are natural products of human metabolism, but consuming high CO2 levels can result in unhealthy symptoms such as sore throat, irritated nose/sinus, combined mucous membrane, tight chest, etc., wheezing. The modern air conditioner is designed to exhaust polluted indoor air. Ventilation is not an issue for those who rich enough. But indoor polluted air is a big problem for the middle-class and poor. As part of this study, the homes of 20 middle-class families (Families with at least one Pulmonary patient were chosen) with different numbers of occupants were inspected among 50 selected families. As part of the inspection, the concentration of CO2 in the families' bedrooms was ceaselessly measured over an average of 3 days. An average CO2 concentration was recorded at night in bedrooms of all families, 03 bedrooms had below 1000 ppm, and 17 bedrooms had above 2000 ppm, and in 03 bedrooms had above 4000 ppm. The CO2 concentration was recorded in the identical bedrooms after deploying the developed Automated Ventilation System. Our system and architecture have 100^% of efficiency in maintaining the bedroom CO2 concentration below 1000 ppm.
