2.2 Working Principles
Conceptual Diagram
The Sensor can convert the voltage and current signal to be the signal that can be identified by
MCU through the sampling circuit, MCU will calculate and convert it into energy, power,
power factor and other electrical quantity by calculating the signals in the sampling circuit,
transferring to users through communication and meanwhile save the data in the storage
circuit. Please see the conceptual diagram of the Sensor as Figure 2-2 Conceptual diagram.
