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.

Power measuring system and power measuring method

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.

Method for sensing power consumption and sensing device

An air velocity sensing system not requiring external power supply is applied to an air duct system, comprising: (1) a sensor module disposed in the air duct for measuring the air velocity therein and for saving the measured air velocity value; and (2) a control module for wirelessly transmitting a signal to the sensor module, which sends the measured air velocity value back to the control module after receiving the signal from the control module, so as to have the air velocity value displayed on control module. The present invention also provides an air velocity sensing method not requiring external power supply.
