“This is a IOT based Power and Energy Meter with Blynk iot platform.
In this project I’ll show you how to make a IOT based power and energy meter which can measure current, power, energy consumption using INA219 current sensor and shows it on OLED display and to blynk app through internet. In blynk app you can see the graphically representation of your voltage, current, power and energy data.
How to make it?
To make this project you will need some component
Arduino Pro mini
INA219 current sensor
0.96” i2c OLED
450mah lipo (capacity is optional) with charging circuit.”
