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.
Arduino energy monitor.
The code is shown in the attached images here is the link to download the energy meter code.
1x 9v ac ac power adapter.
Now you can upload your sketch onto your arduino if you haven t uploaded a sketch before then follow this guide on getting started.
1x 100kohm resistor for step down voltage divider.
Ct sensors interfacing with an arduino.
The display the display unit.
All the calculations are done in the digital domain on an arduino.
Introducing the openenergymonitor system.
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.
1x 9v ac ac power adapter 1x 100kohm resistor for step down voltage divider.
Assemble the components per the diagram above.
All the calculations are done in the digital domain on an arduino.
You can use the eagle files to get a professional board made or you can email me and see if i have any on hand for sale.
Note that if etching your own board the through hole parts will be a bear to solder.

The sketch is the software that runs on the arduino.
The arduino energy monitor.
This project creates a real power energy monitor using a nodemcu module with esp8266 12 and ads1115.
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.
Pre assembled open hardware electricity temperature and humidity monitoring units based on the arduino and raspberry pi platforms.
The arduino converts the raw data from its analog input into human readable values then sends them to the serial port monitor.
Smart energy monitor based on arduino project tutorial by mohamed maher.
Wiring up the circuit.
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.
Step one gather components.
First a quick look at the installed setup.
This basic version is for apparent power only.
The energy monitor can calculate real power apparent power power factor rms voltage rms current.
Open source smart energy monitor with some new features like terminal commands readings logger and data plotting.
Step one gather components.
