Introduction:
A motion detector is a device that contains a motion sensor that detects moving objects and transforms the detection of motion into an electric signal. A sensor is basically a device that receives a stimulus and responds with an electrical signal. The process of receiving a stimuli and giving a response is referred to as sensing. Sensing activities may include collection of values for temperature ,vibration,pulse,humidity and other health-related information and data
It is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area. Motion detectors form a vital component of security, automated lighting control, home control, energy efficiency, and other useful systems
