In recent trends, smart buildings have become the base for the Internet of Things (IoT). The usage of the internet is increased by connecting the devices in the homes to make the places more comfortable, provident, delightful, and secure. Traditional house locks are getting out of date. Smart door lock is commonly used nowadays in most homes. Smart door lock looks more sophisticated and makes home security safer. With smart door lock you don't have to physically open the door. Smart door locks are also not like other digital doors but are otherwise operated via Wi-Fi. Time is not wasted finding the door lock because the smart door lock can remotely lock the door. The proposed approach addresses a security aspect in smart home technologies, namely the door lock system. The door lock system determines the security by allowing the owner to monitor the buildings with a Smartphonecontrolled, Wi-Fi-connected system using NodeMCU ESP32. A microcontroller is chosen for this project is built to experiment and develop security breaches. Users can open or close the door lock by installing the developed android application on devices like tablets, smartphones, laptops, etc. by providing login credentials.
