This project creates a real power energy monitor using a nodemcu module with esp8266 12 and ads1115.
Arduino energy monitor.
1x 100kohm resistor for step down voltage divider.
Ct sensors interfacing with an arduino.
Pre assembled open hardware electricity temperature and humidity monitoring units based on the arduino and raspberry pi platforms.
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.
Assemble the components per the diagram above.

The energy monitor can calculate real power apparent power power factor rms voltage rms current.
Introducing the openenergymonitor system.
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.
The arduino energy monitor.
Now you can upload your sketch onto your arduino if you haven t uploaded a sketch before then follow this guide on getting started.
The display the display unit.
The sketch is the software that runs on the arduino.
The energy monitor can calculate real power apparent power power factor rms voltage rms current.
Step one gather components.
Open source smart energy monitor with some new features like terminal commands readings logger and data plotting.
Upload the arduino sketch.
1x 9v ac ac power adapter 1x 100kohm resistor for step down voltage divider.
Note that if etching your own board the through hole parts will be a bear to solder.
First a quick look at the installed setup.
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.

Wiring up the circuit.
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.
The code is shown in the attached images here is the link to download the energy meter code.
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.
This basic version is for apparent power only.
All the calculations are done in the digital domain on an arduino.
