Air-kare: A Wi-Fi based, multi-sensor, real-time indoor air quality monitor

A portable, real-time, wireless indoor air monitoring system is designed using the Arduino Yun platform. Because of the importance of a clean indoor environment on human health, the proposed prototype is designed to monitor the temperature, humidity, volatile organic compounds (VOCs) and miniature dust particles. The Arduino Yun platform incorporates an MCU that acquires and sends the data to a Wi-Fi chipset, serving as the communication bridge between the server and clients. Experimental results shows that temperature, humidity, concentration of VOCs and dust particle density can be detected in household with acceptable sensitivities, up to 50m away wirelessly, and charted in real-time with a HTML-5.0 enabled web browser. At the same time, all the historical data are stored in cloud.
