Smart Energy Meter Using Arduino Code

With RS485 port, the multi-channel din rail three phase energy meter can be connected to one data collector/RTU/DTU to
transmit data to management software. The DTU is with built-in communication modem such as Ethernet, NB-IoT, GPRS, 3/4G,
Lora. Etc. and one DTU can manage up to 32 circuits load.

1. Use high precision metering chip to complete the meter metering;
2. With positive and negative active power, and a variety of combined electricity metering functions;
3. Measuring current, voltage, frequency, power factor, with/without power, apparent power;
4. Can record and alarm of undervoltage, overpressure, overpressure and break equal events;
5. On the meter reading day every month, the electric quantity will be settled automatically
6. The meter is capable of timing, timing and daily freezing of the data.
7. LCD digital display, rotate display hour meter parameters;
8. Support time of use function(TOU).
9. Support for multiple rates and multiple periods of metering.
10. The data inside the meter can be read through the RS485 and infrared interface.
11. The electricity meter is installed with standard 35mm din rail.
