Indoor air detection device

The invention discloses an indoor air detection device which comprises a guide rail, the main body of the guide rail is of a rectangular structure, the outer side of the guide rail is fixedly connected with a mounting plate, the mounting plate and the guide rail are vertically mounted, a through groove is formed in the mounting plate, the through groove is a mounting groove, and the guide rail, the mounting plate and the mounting groove jointly form a splicing structure. The main body interface of the guide rail is of an I-shaped structure, a transverse groove is formed in the front end face of the guide rail, and an adjusting assembly is installed in the transverse groove. Compared with the situation that the coverage range of a traditional fixed air detection device is small, the coverage area of the air detection device can be remarkably increased, adjustment of manual intervention is effectively reduced, and the detection efficiency of the current air quality is ensured. 本发明公开了一种室内空气检测装置，包括：导轨，导轨的主体为矩形结构，
