Multiple Function Security System

Student: Nasser Al Sheriff

Introduction and Application

4 functions in on system:
- Light Detector
- Contact Detector
- Motion Detector
- Pressure Detector

Make a security system that would protect any valuable part of the house.

Each detector can be used in different part of the house for different purposes. 
- Light detector can be placed in a cabinet or a drawer. 
- Contact detector can be placed on a door handle.
- Motion detector can trigger any motion in the house or the backyard.
- Pressure detector can be placed under a doormat.
- All of these sensors can trigger an action such as a light or a video camera, etc.
