The number of boost chips included in the power adjustable unit 1111 is set according to actual needs. Figure 3 In the example, the power adjustable unit 1111 includes two boost chips. Specifically, the boost chip U1 can be a MAX1932 boost chip.
[0050] In order to make the power supply voltage output by the adjustable power unit 1111 more stable, the adjustable power unit 1111 includes a voltage stabilizing and current limiting circuit, the input end of the voltage stabilizing and current limiting circuit is electrically connected to the output end of the boost chip, and the output end of the voltage stabilizing and current limiting circuit is electrically connected to the first power supply interface 1211. The voltage stabilizing and current limiting circuit is used to make the adjustable power unit 1111 output the power supply voltage stably and limit the current output by the adjustable power unit 1111.
[0051] In some implementations, the control module is used to adjust the supply voltage output by the adjustable power unit 1111.

The first positive buck chip U3 converts a 24V voltage into a +6.5V voltage, and the second positive buck chip U4 converts a +6.5V voltage into a +5V voltage. The number of the second positive buck chips U4 can be set according to actual use. For example, if the amplification module of the light sensor requires 1 +5V voltage, the number of the second positive buck chips U4 is 1; if the amplification module of the light sensor requires 2 +5V voltages, the number of the second positive buck chips U4 is 2. Specifically, the first buck chip U3 can be a TPS5430 chip, and the second positive buck chip U4 can be a LM337IMPX / NOPB chip.

For example, if the light sensor requires 1 -5V voltage, the number of the second negative buck chips U6 is 1; if the light sensor requires 2 -5V voltages, the number of the second negative buck chips U6 is 2. Specifically, the first buck chip U5 can be a TPS5430 chip, and the second negative buck chip U6 can be a LM337IMPX / NOPB chip.
