Proteus Simulation and Implementation of an Arduino Mega-Based Motion Detection Alarm System

Security is of paramount importance in this modern world, as it provides protection for human life and property from criminals. Lack of proper security has resulted in sexual harassment of innocent women, many deaths, and theft of large sums of money and property. This project therefore seeks to design a motion detection alarm system using a microcontroller that will help reduce the percentage of burglaries and minimize the menaces or challenges associated with a lack of proper security. Motion detection was accomplished with the help of the passive infrared (PIR) sensor, which has a “field of view†angle of 110 ̊ and measures thermal infrared radiation emitted from the human body. The Arduino Mega 2560 microcontroller board was programmed using the Arduino IDE software to continuously monitor the PIR sensor’s output and enhance motion detection by activating an LED or triggering the piezo buzzer. Additionally, the designed circuit was simulated using the Proteus 8.2 design suite, and a prototype was built to confirm its functionality. The obtained results indicate that the motion detection system successfully responds to changes in the PIR sensor’s output. Overall, this motion detection alarm system is efficient, cost-effective, and enhances security measures.
