<![CDATA[This research aims to develop a home access security system with a combination of Arduino-based sensors and buzzer methods and to address the problem of home downtime. This research has 3 methods, namely observation, laboratory research, and library study. This study was created to develop a tool for detecting a car using a PIR sensor that can be controlled using a smartphone and notifications directly go to the Telegram application that can be monitored anywhere and anytime, so that when homeowners live for a long period of time they are not too worried while the tool we created uses sensors located on 4 sides of the house. In the design of this tool, the author hopes that it can be developed to be more sophisticated and have even more useful benefits.
