Abstract: A method for measuring electric power includes: mounting a sensing device on a wire between a capturing device and an electronic goods, wherein the capturing device is used for capturing a total power consumption value of the wire; measuring a relative electricity value of the wire using the sensing device; establishing a solution model based on the relative electricity value to output a loop power consumption result of the wire; determining whether the solution model satisfies a predefined condition, wherein the predefined condition includes the loop power consumption result of the wire being close to the power consumption value captured by the capturing device; and when the solution model satisfies the condition, outputting an absolute electricity value of the wire.

Abstract: A sensing device includes a housing positioned on an outer surface of a wire and a circuit board received in the housing. The circuit board has a sensing area for sensing the wire, such that the measurements obtained by the circuit board are relative values. Therefore, the circuit design of the circuit board can be simplified, and the size of the sensing device can be reduced.

Abstract: A water body self-generating electrolytic reduction module is applied to a water body containing oxidizing substances. The water body self-generating electrolytic reduction module includes a self-generating unit and an electrolysis unit. The self-generating unit is coupled to the electrolysis unit. When circulating in a water transmission pipeline, the water body drives the self-generating unit to generate an electric power and deliver the electric power to the electrolysis unit. Upon receiving the electric power, the electrolysis unit performs electrolysis on the water body circulating to the electrolysis unit, so that a reduction reaction occurs to the oxidizing substances in the water body.
