Peacefair is a very famous chinese brand with good quality and price that specialize in metering products.
Arduino ac energy meter.
Its also really easy to add your local tariff and display the cost of electricity used to date.
Circuit diagram of power factor meter using arduino consists of current sensor and voltage sensor circuits.
Arduino energy meter v2 0 in this tutorial i am going to show you how to make a simple wifi enabled ac energy meter by using arduino wemos board.
So this meter measures the supply current to your home through a ct current transformer and then does a couple of calculations to give you your current power maximum power and kilowatt hours consumed.
The calculated power and energy by the arduino wemos is displayed on a 0 96 oled display module.
Current sensor circuit use acs712 current sensor and voltage sensor circuit consists of step down transformer and voltage divider circuit.
No warranty is provided with this project do it at your own risk.
By using this energy meter you can measure the power consumption of any home appliances.
This post shows how to build a simple ac voltmeter that measure ac voltage with arduino uno board where voltage value is printed on 16 2 lcd screen.
Once the analog input is given to arduino the measurement of power energy is done by arduino sketch.
At the end of the project i made a nice 3d printed enclosure for this project.
