Now you can upload your sketch onto your arduino if you haven t uploaded a sketch before then follow this guide on getting started.
Arduino energy monitor.
Introducing the openenergymonitor system.
This page and linked pages detailed below document how to build whole house energy monitor that has a display for easy quick access to current energy use information usb datalogging for detailed long term data storage and internet connectivity for online graphing.
The energy monitor can calculate real power apparent power power factor rms voltage rms current.
All the calculations are done in the digital domain on an arduino.
This project creates a real power energy monitor using a nodemcu module with esp8266 12 and ads1115.

This basic version is for apparent power only.

First a quick look at the installed setup.
Upload the arduino sketch.
The sketch is the software that runs on the arduino.
All the calculations are done in the digital domain on an arduino.
Note that if etching your own board the through hole parts will be a bear to solder.
1x 9v ac ac power adapter 1x 100kohm resistor for step down voltage divider.
Attached to this step are the eagle schematics and board layouts for the arduino energy monitor shield as well as pdfs for printing and using the toner method for etching your own pcb.

Smart energy monitor based on arduino project tutorial by mohamed maher.
Step one gather components.
Because your setup ct resistors and input voltage may be different there is a scaling factor in the sketch which you will need to change before you will get.
Ct sensors interfacing with an arduino.
Step one gather components.
Open source smart energy monitor with some new features like terminal commands readings logger and data plotting.
Assemble the components per the diagram above.
The display the display unit.
The energy monitor can calculate real power apparent power power factor rms voltage rms current.
To keep component count low and the circuit as simple as possible the ads1115 is used in differential mode eliminating the need for bias resistors.
The arduino converts the raw data from its analog input into human readable values then sends them to the serial port monitor.
