Introduction: Make Your Own Power Meter/Logger
In this project I will show you how I combined an Arduino, an INA219 power monitor IC, an OLED LCD and a Micro SD Card PCB in order to create a power meter/logger that has more functions than the popular USB Power Meter. Let's get started!
Step 1: Watch the Video!
The video gives you a good overview on how to create your own power meter. In the next steps though I will present you some additional information to make this project even simpler.
Step 2: Order Your Parts!
Here you can find a parts list with example seller for the portable version of this project.

Step 3: Create the Circuit!
Here you can find the schematic for the Arduino Nano version and the portable version of this project. You can also find those schematic on the EasyEDA website:
You can also use the pictures of my finished board as a reference for your own.
Step 4: Upload the Code!
Step 5: Success!
You did it! You just created your own Power Meter/Logger

can this circuit measure ac voltage and current for live ac loads
hi, congrats and thanks for a great video. I want to make a similar project but i need to monitor more current like upto 24 volts and 21 Apms.......what you suggest i do, or replace in the your given circuit? Hope to get a quick reply.
How accurate is this? Or the minimum watt measured by it?
Can this technically be used as a power supply volt amp meter?
