Mobile terminal-based air quality detection device and method

The invention discloses a mobile terminal-based air quality detection device and method. The device comprises an audio plug, a modulation/demodulation module, an air dust detection module and a power module, wherein the device is physically connected with a mobile terminal by the audio plug, and by virtue of modulation and demodulation of the modulation/demodulation module, the data communication between the air dust detection module and the mobile terminal can be realized. The device effectively utilizes functions of data processing, displaying, command input and the like of the mobile terminal to achieve air detection, air quality analysis and other derivative functions related to air quality detection; compared with a traditional air quality detection device, the mobile terminal-based air quality detection device also has the advantages of being convenient to carry, low in manufacturing cost, etc.
