Air pollution is one of environmental contaminations due to various factors, outside and inside the room. Based on NIOSH (National Institute for Occupational Safety and Health), the safety level of carbondioxide for humans is less than 1000 ppm. In this research, a system based on ATmega8535 for supporting CO2 meter voltcraft CM-100 and SHT11 is developed. The experiment consists of three stages, design and construction of the air quality monitoring systems, data acquisition and data analysis. There are four scenarios to test the system. Smoky weather, rain weather, measurements of carbon dioxide levels in the room with variations of ventilation and variations in the number of occupants in the room. The results show that the amount of carbondioxide concentration on 621 ppm while the minimum value is 426 ppm. On the rain the maximum and minimum carbondioxide is 518 ppm and 426 ppm. For intersection of accupant and ventilation variable, the maximum and minimum carbondioxide is 1535 ppm and 467 ppm respectively. The moisture measurement scenario with SHT11 sensor for smoky weather has maximum value at 83.9%, the and minimum 71.0%, on the rain weather maximum value obtained at 85.8% and 77.3% for minimum. While the occupant’s variation and variation of ventilation obtained maximum humidity value at 82.7% with a minimum value at 68.7%.
