Therefore, it is necessary to create a fresh air, healthy and comfortable living environment for our family and friends. Indoor air quality detection is a newly rising industry. The industry will give a air pollution detection, which through detecting pollution caused by the indoor decoration, furniture and so on. It issued a national authority and legal detection report. Through the detection report, we can see the concentration of indoor pollution substances, and then take some measures to prevent the pollution. The air quality detector is consist of a sensor, Zigbee module and PC, which is based on a wireless sensor network of Zigbee to detect indoor air quality. The first step is collect data, which though a variety of sensors of indoor formaldehyde, such as benzene, ammonia, total volatile organic compound TVOC and other air pollutants sensors. The second step is data transmission, which transport the test parameters to the Zigbee terminal node. The third step, the main control end display and monitor the air quality index, which will receive the number through the Zig
