Motion Sensor Security System using (PIR)

By Essam.M.Haider

Introduction * The project itself is a motion sensor security system capable of detecting the presence of body heat in any designated area.

* State of the art motion detectors use the most modern techniques to eliminate factors causing interference, which affect reliability, to guarantee superior long-term performance and reduce false alarms.

 

Project Objective

* The goals of the alarm system are to detect heat movements in a specified area triggering a siren/buzzer to sound.   * This design promotes added control to the crime rate of the regulated work environment after hours of work operation. It also cuts down on expenditure costs on human resources because you don’t need any operator to make work out.
