| A lot of big cities serious haze phenomenon, urban housing renovation, all kinds of untreated chemical composition in the air of the spread, will cause harm to people’s health. Due to the improvement of people’s living standards and environmental awareness, indoor air testing has also entered the civil use of smart home. Current research status of indoor air quality products. The indoor air quality testing as the breakthrough point, arm micro controller as the embedded development platform, combined with the Bluetooth wireless transmission technology, a portable, low power consumption, indoor air quality detection system is designed.In this paper, detailing the design of indoor air quality testing system, sensor selection and application circuit design, Bluetooth protocol stack characteristics and application, intelligent terminal development, complete the design of the detection system.Communication between intelligent terminal and wireless Bluetooth devices transmission technology. At last, the test system is tested, and the data communication test between Bluetooth and intelligent terminal is tested. Finally completes the test system to carry on the function test, the blue tooth and the intelligent terminal data communication test.The results show that the indoor air quality detection system designed in this paper can realize real-time detection of indoor air. Detection system has the advantages of low power consumption, portable, intelligent and so on, for people living in a healthy indoor environment to provide a guarantee. |
