Summary of Make Your Own Power Meter/Logger
This project details the construction of a portable power meter/logger using an Arduino Pro Mini, INA219 power monitor, OLED LCD, and Micro SD Card PCB. The device offers enhanced functionality compared to standard USB power meters by logging data and displaying real-time metrics on a screen. It includes a LiPo battery and TP4056 charging board for portability, controlled via a switch.
Parts used in the Portable Power Meter/Logger:
- LiPo Battery
- TP4056 Board
- Arduino Pro Mini
- INA219 Board
- OLED LCD
- SD Card PCB
- Switch
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.
