At the same time, the position acquisition module in the positioning component 3 obtains the position information of the monitoring device in real time, and the trajectory generation module generates a moving trajectory. The data processing module in the control component 4 receives the electrical signal, and further converts it into a digital signal representing the numerical value of the PM2.5 concentration of particulate matter in the air.

[0035] Compared with the prior art, the particulate matter PM2.5 monitoring device provided in this embodiment detects the concentration of particulate matter PM2.5 in the air in real time through the monitoring component and generates an electrical signal. The positioning component obtains the location information of the monitoring device in real time and generates a moving trajectory.

By increasing the surface area of ​​the heat dissipation component or using a fan to increase air flow, the heat dissipation efficiency can be improved, ensuring that the control component 4 maintains a good operating temperature range during long-term use.
