Introducing the openenergymonitor system.
Arduino energy monitor.
This project creates a real power energy monitor using a nodemcu module with esp8266 12 and ads1115.
Open source smart energy monitor with some new features like terminal commands readings logger and data plotting.
The code is shown in the attached images here is the link to download the energy meter code.
1x 100kohm resistor for step down voltage divider.
The sketch is the software that runs on the arduino.
The arduino energy monitor read 17952 times previous topic next topic.
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.
Note that if etching your own board the through hole parts will be a bear to solder.
Upload the arduino sketch.

1x 9v ac ac power adapter.
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.
Step one gather components.

The arduino energy monitor.
The display the display unit.
The energy monitor can calculate real power apparent power power factor rms voltage rms current.
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.
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.
Now you can upload your sketch onto your arduino if you haven t uploaded a sketch before then follow this guide on getting started.
First a quick look at the installed setup.
All the calculations are done in the digital domain on an arduino.
The arduino converts the raw data from its analog input into human readable values then sends them to the serial port monitor.
Wiring up the circuit.
Ct sensors interfacing with 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.
Assemble the components per the diagram above.
Step one gather components.
