Every management system is trying to make an automatic, portable, accurate and reliable system to for measurement. This project work presents a novel smart meter for an automatic and superior metering, billing and warning system. The integration of the Arduino and LCD provide the meter reading system with some automatic functions that are pre-defined. The proposed energy meter system can incorporate with an embedded microcontroller and PZEM-004T AC Digital Multifunction Meter designed by Peacefair . PZEM-004T having the ability to measure Electrical parameters such as voltage, current, active power and energy, power factor and frequency. Measured parameters are directly transmitted with TTL serial interface with Arduino nano board and display on 16*2 LCD Display.
Our implemented project is able to provide all required measurements for metering and billing with high fidelity. Some of the special features of our project is
- Overload alarm function
- AC Voltage and Current Measurement with a range of 80 ~ 260VAC which cover major country voltage range like 110V and 230V and 0 ~ 100A current measurement capability.
- Power measurment range is 0 ~ 22kW and energy range 0 ~ 9999kWh.
- Frequency mesurment
- Power Factor measurment
