The fuzzy logic method plays a role in determining the decision in the home security system whether the house is safe or not based on the input value of the reading from the installed sensor. The method applied in this research is fuzzy logic method. The home security system consists of PIR (Passive Infra Red) sensor that acts as human motion detectors, ultrasonic sensor that serves to measure the distance when humans are detected outside the home, and a magnetic switch that serves to detect whether the door of the house is opened or closed, the three sensors are integrated with the arduino microcontroller device as the control center.
Based on these thoughts the writer makes a home security system that can monitor the house and provide early warning to the homeowner if unknown person is detected entering the house. Frequent occurrence of crime at home requires creating an integrated security system with smartphone devices so that home owners can monitor his house in realtime. Likewise with technology based home security systems. The era of globalization has demanded humans to create security in everyday life. The need for security is one of the most important things in human life.
