IOT Implementation Plan For Anti-Theft Alarm System Using Pir Sensor

Abstract

A house is the main need for shelter for everyone. We must look after and maintain all household equipment and the items in it properly. However, theft of home property usually occurs when the house is empty. This research aims to help secure a room with a room security system by providing a warning in the form of a sound indicator from a buzzer and sending a message from the GSM SIM to the cellphone. The room security system was designed using the prototype method. The results of this research show that the system and tools are able to run well. The PIR sensor is capable of detecting movement at a distance of 5 meters and is able to provide alerts in the form of a buzzer sound and send messages. So that these systems and tools can be applied to room security in everyday life. This security system uses an Arduino Uno r3 microcontroller which is connected to a PIR sensor, Buz/Buzzer and Slideswitch (Slide Switch). The PIR sensor will detect movement that causes changes in voltage. The change in voltage from the sensor will then be used as input data by the micro controller and processed so that the LCD lights up and the buzzer/alarm sounds. This security system is able to detect the presence of humans who enter the sensor's coverage area, then the body temperature emitted by the human will be detected and then the sensor will be active.
