Introduction* The project Audio Visual Motion Sensor using a PIR sensor itself iscapable of detecting slightest amount of motion.
* A motion sensor is a device for motion detection i.e. a device thatcontains a physical mechanism or electronic sensor thatquantifies motion that can be either integrated with or connected toother devices that alert the user of the presence of a moving object
within the field of view. They form a vital component ofcomprehensive security systems, for both homes and businesses..

PIR MOTION SENSOR
* Apassive Infrared sensor (PIR sensor) is anelectronic sensor that measures infrared (IR) light radiating fromobjects in its field of view. They are most often used in PIR-basedmotion detectors.
* The goals of the motion sensor system are to detectmovements in a specified area triggering a siren/buzzer tosound or to light a LED.
* This design promotes added control to the crime rate of the
regulated work environment after hours of work operation. Italso cuts down on expenditure costs on human resourcesbecause you dont need any operator to make work out.
