Single Phase LoRaWAN Smart Electric Meter

Introduction:

DDS155 series BR (LoRaWAN) single phase electric meter is a kind of fully digitized energy meter which adopts the SOC high-density V9821S chip. Besides measure active energy, it also has function for online power display, smart anti-tamper, overload control, remote meter reading and etc. It sends data to corresponding gateway through LoRaWAN wireless network. It has advantages in high accuracy, low power consumption, and good stability that can be widely used for the single phase alternating current in city, rural areas or factory enterprises, etc.
