What is Motion Detector?

By Ashutosh Bhatt September 21, 2011

Motion Detectors are the electronic/mechanical devices which detects the motion/movement of an object by accurate measurement of its speed and other vectors. An electronic motion detector incorporates a motion sensor which measures the optical and acoustical changes in the field of view and converts them into corresponding electrical signals.
 
These motion detectors are mainly used in the ‘burglar alarms’ and advanced video games.
