Abstract: This research assesses the creation of a low-cost security system based on a microcontroller and a tiny PIR (Pyroelectric Infrared) sensor. Because of the frequent and widespread incidents of burglary, the requirement for effective and accurate intrusion detection with an alarm system has become a critical necessity. Attacks on home offices, factories, banks, and other institutions are on the rise. Motion can now be detected by measuring the change in speed or vector of an object in the field of view, thanks to technological improvements. The motion detector is utilized in a variety of applications, including home automation systems, energy efficiency systems, and more. This project is made with an embedded microcontroller system capable of detecting intruder motion in a restricted area and then triggering an alarm system, motion detector system. However, pyroelectric infrared sensor identified the person's motion using the person's body heat. The motion detector in this project is a pyroelectric infrared (pir) sensor that is connected to a microcontroller that activates the alarm system and any other attached output device to warn the house owner. The concept passed the initial testing with flying colours.
