1 Multiple Function Security System

2 INTRODUCTION & 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.

3 SPECIFICATION Part 1 : Light Detector: On / Off Switch LED Light sensor MAL 12 phototransistor Part 2 : Contact Detector: On/ off switch LED Contact Plate ( 2.5 X 2.5)SI Part 3 : Motion Detector: On/Off switch KC778B (20 pin DIP) Voltage regulator 78L05 Fresnel Lens with diameter of 1/2 an inch Detection range: 3m- 4 m. View Field is 125 degree 3 Controllers: Motion sensitivity control PIR Time Control (time Adjustment) from 1.5 sec to 15 sec. Daylight sensitivity control Part 4: Pressure Detector: 4 Pressure sensors (832) Load range:.001pound- 100 pound. 4 LEDs “indicators” each sensor Part 5: Response Circuit: Different LED Different buzzers for each detector
