3. other things include :

   • sensor
     • motion sensor
       • a motion sensor (or motion detector) is the linchpin of your security system, because it's the main device that detects when someone is in your home when they shouldn't be. A motion sensor uses one or multiple technologies to detect movement in an area.
     • other sensors include :
       • Proximity Sensor. Accelerometer. IR Sensor (Infrared Sensor) Pressure Sensor. Light Sensor. Ultrasonic Sensor. Smoke, Gas and Alcohol Sensor.
