DIY Device that Monitors the Power Grid of the Entire Country

The power grid is one of the most critical systems in our modern world, but we often take it for granted until it fails. In this video, we show you how to monitor the power grid of the entire country with a simple device. Using an ESP8266 board and an optocoupler, we measure the oscillations in the power grid and calculate its frequency with high precision. We take you step by step through the process of building the circuit and testing it, also we provide the code for programming the ESP8266. With the help of a slow-motion camera, we demonstrate the fascinating property of frequency synchronization in the power grid. This video is a must-watch for anyone interested in electronics, energy systems, and the power grid. The code for the project and the list of components can be found her ...
