Open source smart energy monitor with some new features like terminal commands readings logger and data plotting.
Arduino energy monitor.
Smart energy monitor based on arduino project tutorial by mohamed maher.
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 energy monitor can calculate real power apparent power power factor rms voltage rms current.
Pre assembled open hardware electricity temperature and humidity monitoring units based on the arduino and raspberry pi platforms.
All the calculations are done in the digital domain on an arduino.
1x 9v ac ac power adapter 1x 100kohm resistor for step down voltage divider.
1x 100kohm resistor for step down voltage divider.
Wiring up the circuit.
The sketch is the software that runs on the arduino.
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.
First a quick look at the installed setup.
Upload the arduino sketch.
The code is shown in the attached images here is the link to download the energy meter code.

1x 9v ac ac power adapter.
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.
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.
Ct sensors interfacing with an arduino.
Step one gather components.
Assemble the components per the diagram above.
Introducing the openenergymonitor system.
The arduino converts the raw data from its analog input into human readable values then sends them to the serial port monitor.
This basic version is for apparent power only.
All the calculations are done in the digital domain on an arduino.
The energy monitor can calculate real power apparent power power factor rms voltage rms current.
Step one gather components.
Now you can upload your sketch onto your arduino if you haven t uploaded a sketch before then follow this guide on getting started.
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.
Note that if etching your own board the through hole parts will be a bear to solder.
