A PIR (Passive Infrared) Based Motion Detector Alarm is a security device designed to detect human motion and trigger an alert. It uses a PIR sensor to sense infrared radiation emitted by warm objects, such as humans or animals, within its detection range. When the sensor detects movement, it sends a signal to an alarm system or buzzer, which then activates an audible or visual alert. This system is commonly used in home security, offices, and restricted areas to monitor unauthorized entry or movement. It is energy-efficient, cost-effective, and easy to install, making it ideal for both residential and commercial applications.
