[0021] In this embodiment, the protective shell 2 can be smoothly moved up and down by connecting the precise threaded sleeve 17 with the screw rod 15 and binding the connecting rod 16 with the lifting sleeve 11. Driven by the screw rod 15, the protective shell 2 can be flexibly raised and lowered according to environmental conditions to optimize the heat dissipation effect and ensure the normal operation of the dust concentration sensor 1 in a high temperature environment. In addition, this design can also quickly lower the protective shell 2 to protect the dust concentration sensor 1 in the face of natural disasters.
