In the first preferred embodiment, the power-on relationship of the output unit 40 can be a power terminal of a smart door lock product or a power terminal of a flash drive.

The actuation characteristics and the efficacy of the first preferred embodiment are compared to conventional techniques. The significant difference is that when the power control module 10 with multiple distance sensing is installed at the power end of the smart door lock product or the power end of the flash drive, the first wireless is transmitted through the first wireless The transmitter 23 wirelessly receives a signal S1 from an external source (not shown, such as a cell phone or a transmitter), and transmits the signal S1 to the first microprocessor 21, and the first The microprocessor 21 converts the signal S1 by the calculation logic 212, and determines the strength of the signal S1 according to the calculation logic 212 during the conversion, and further converts the signal S1 into a data D1 representing a strong state; Wherein, the strength and weakness of the data D1 are defined to correspond to a transmission channel 302 respectively (for example, when the data D1 is strong, corresponding to a certain transmission channel 302, when the data D1 is weak, the corresponding Another of the transmission channels 302), the data selector 30 selects a corresponding one of the transmission channels 302 according to the data D1; when the data selector 30 selects the one When the transmission channel 302 is directly or indirectly electrically connected to the transmission channel 302 of the power switch of the output unit 40, the power switch of the output unit 40 is electrically connected to the first microprocessor by the data selector 30. 21, which in turn can be turned on or off by the control of the first microprocessor 21.
