[0002] Although it is easy to find local air quality conditions on TV, mobile phones and computers, people can often only find the average air quality level in an area over a period of time. Such information can neither meet people's requirements for obtaining local environmental quality anytime and anywhere, nor meet people's needs for simple and fast air quality testing.

[0003] Existing mobile environmental parameter detection equipment either only detects temperature and humidity or only detects formaldehyde, and there is almost no environmental detection equipment that can detect multiple parameters at the same time. At the same time, most environmental parameter detectors use non-renewable energy to power them, which not only wastes huge energy and pollutes the environment, but also the use of the instrument is restricted by the site.

[0004] Therefore, it is imperative to study a detection device that can be carried by a drone and combined with solar energy and can simultaneously detect multiple environmental parameters. Summary of the invention

The real-time environmental information is displayed through the LCD display module provided. At the same time, the Bluetooth module and the 4G wireless communication module will also send the collected data to the terminal APP, achieving the effect of real-time detection of air quality, and can be remotely transmitted to the cloud information management system, so that people can grasp the overall local air quality status more conveniently and timely.
