Smart electricity meters are gradually developed from traditional electricity meters. Smart electricity meter is the smart terminal of smart grid, representing the development direction of intelligent terminal for the end user of energy-saving smart grid in the future. In addition to the basic power consumption measurement function of traditional electricity meters, smart meters also have multiple functions to adapt to the use of smart grid and new energy:
Time sharing multiple rate function
Electric energy metering function
Client control function
Display and storage function
Bi directional data communication function of multiple data transmission modes
Intelligent functions such as electricity theft prevention

The intelligent electricity meter processes the voltage and current signals adopted by the integrated circuit of the electricity meter through the real-time sampling of the user's power supply voltage and current, and converts them into the pulse output proportional to the electric energy. Finally, the pulse is displayed as the electricity consumption and output through the processing control of the single chip microcomputer. How to realize voltage and current sampling? At this time, our metering module can help solve this problem.
