Energy meter is a very useful device that displays important information of electrical parameters.
Arduino energy meter sensor.
There are 4 important electrical parameters in a direct current.
Since this meter only.
According to this voltage and current arduino does the maths for calculating power and energy.
By using this energy meter you can measure the power consumption of any home appliances.
This video guide shows you how to build your own energy meter for use around the home using an arudino and a current transformer ct.
The heart of the energy meter is an arduino pro micro board.
Once you get your resistors current sensor module and arduino board ready you may start to do hardware wiring.
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.
The goal of creating more awa.
In this tutorial i am going to show you how to make a simple wifi enabled ac energy meter by using arduino wemos board.
Once the analog input is given to arduino the measurement of power energy is done by arduino sketch.
Below is the schematic of the whole wiring.
The arduino senses the current and voltage by using the ina219 current sensor and temperature is sensed by temperature sensor ds18b20.
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.
Lcd is interfaced with arduino to display measured voltage on lcd.
