In the blackbody radiation spectrum diagram, a peak is usually seen, which corresponds to the maximum intensity wavelength of the blackbody radiation. As the temperature increases, the curve of the blackbody radiation spectrum diagram will move toward a shorter wavelength as a whole, and the peak intensity will also increase.

[0034] Combine Figure 2 and Figure 3 The output end of the first motor 4 is fixedly connected to the screw rod 3, and the surface of the screw rod 3 is threadedly connected to the second nut pair 5.

Then, when using it again, the first motor 4 can be started to drive the screw rod 3 to rotate, drive the second nut pair 5 to move up and down, and drive the support plate 9 to move up and down. Then start the second motor 8 to work, and different areas can be detected. Then manually rotate the protrusion 13 to drive the threaded rod 12 to rotate in the first nut pair 14, and then drive the threaded rod 12 to rotate in the limit ring 15, so that the threaded rod 12 is adjusted, and the smoke alarm 16 below is driven to move in the groove 10.
