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.
Claims20
A method for sensing power consumption, comprising:
- sensing, by a sensing device, a change in a waveform of a current or a voltage on a wire;
- performing integration operation and digital processing on the waveform of the current or the voltage;
- and
- calculating a root mean square of a value of the current or the voltage, wherein the value of the current or the voltage is a relative value.
