Smart home automation systems can work thanks to the Internet of Things (IoT). These tools make homes safer and more pleasant. With this article, you'll learn how to build a smart door control system that works with an ESP32 microcontroller that has Wi-Fi. The device has a keypad that only permits people who are allowed to open the door do so. When the password is checked, a servo motor turns on and opens and closes the door by itself. A controlled power source keeps everything running smoothly and stops parts from breaking out. Tests show that the system works well, responds promptly, and handles passwords correctly. The suggested procedure is safer and superior than the ones that came before it. It might also have more functions in the future, like being able to control it via a mobile app, log in using biometrics, and keep a watch on it from the cloud.
