[0011] Such as figure 1 Shown is a schematic diagram of the structure of a solar-based PM2.5 detection system. The system includes a solar battery 1, a full-color LED light 2, a liquid crystal display 3, a single-chip computer 4, a PC 5, a dust sensor 6 and a temperature and humidity sensor 7; the solar battery 1. The full-color LED light 2, the liquid crystal display 3, the dust sensor 6, and the temperature and humidity sensor 7 are all connected to the single-chip computer 4 through wires, and the single-chip computer 4 is connected to the PC 5 through a chip.
[0012] Such as figure 2 As shown in the temperature and humidity detection flow chart, the system temperature and humidity detection is achieved through the following steps. Step 1: Turn on the entire system and enter initialization; Step 2: The program executes to check whether the temperature and humidity sensor responds, if the sensor does not respond, return; Step 3: The single-chip microcomputer reads the temperat...
