Effectual Home Automation using ESP32 NodeMCU

The fourth technology revolution is the one we're in right now. As we live in a time where the internet and its use are constantly expanding. The idea of a smart device is growing in acceptance. The availability of web and software system technologies is making our lives easier. A smart house could be one of the major features of IoT. In this paper, we offer an inexpensive, useful, and Internet of Things-based home automation system. The Blynk ASCII text file IoT server supports this technique. In our project, the Esp32 module may link a server to the internet, allowing us to operate any linked home appliances. Between the esp32 and the electrical appliances, there will be a relay that controls the 230-volt appliances by switching a certain low voltage from the esp32.
