！ ！ ！ ！ Note

Except for dust (PM), which uses infrared sensors, the rest of the parameters tested use semiconductor sensors. The data is directional and not quantitative (the detection is an approximate data range, and the data cannot be accurately guaranteed). It focuses on high cost performance and multi-function and multi-parameter.
