Arduino Ac Energy Meter

Its also really easy to add your local tariff and display the cost of electricity used to date.

Arduino ac energy meter.

By using this energy meter you can measure the power consumption of any home appliances. At the end of the project i made a nice 3d printed enclosure for this project. The calculated power and energy by the arduino wemos is displayed on a 0 96 oled display module. Peacefair is a very famous chinese brand with good quality and price that specialize in metering products.

Once the analog input is given to arduino the measurement of power energy is done by arduino sketch. Circuit diagram of power factor meter using arduino consists of current sensor and voltage sensor circuits. 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. Pzem 014 or 016 ac energy meter with arduino.

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. Current sensor circuit use acs712 current sensor and voltage sensor circuit consists of step down transformer and voltage divider circuit. 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. Pzem 014 measurement up to 10a direct connection and pzem 016 measurement up to 100a indirect connection using current transformer are ac energy meterfrom peacefair.

The ac current passing through the load is sensed by the current sensor module acs712 and fed to the analog pin a0 of the arduino wemos board.
