Motion sensor is device consists of physical or electronic mechanism with other device to sense the movable objects.
It actually consists of motion sensor which transmit the motions into the electric signals, which is then connected to a LED light or burglar alarms to provide the alert.
Types of sensors:
1. Passive Infra red Sensor --- Detect body heat
2. Ultrasonic Sensor --- Detect moving object by sending ultrasonic pulse waves
3, Microwave --- Sense the moving object by sending the microwave pulse
4. Tomographic --- Sense the Disturbance in radio waves by traveling through mesh network.
Nowadays PIR technology uses to sense in better way and avoid any false detection. For more accuracy this is
used, but to know what is happening to behind the wall for this motion-sensitive outdoor lightning is recommended.
