Smart-Home-Automation-System

The smart home automation system integrates YOLO (You Only Look Once) object detection technology to monitor and control various aspects of the home environment. Without any intervention of Iot devices. #-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
