2 OUTLINE Motivation Original Idea Problem Statement Results Conclusion Future Work

3 MOTIVATION Home security is an important topic to everyone. I like working with PLC’s. It is something that PLC’s have not really ever been used for. It also cost a lot for a home security system.

4 INTRODUCTION PLC’s are most commonly used in an industrial settings. It is a device that can handle a bunch of different inputs and outputs. Which makes it ideal for a security system that has to have be versatile. All of the controls are run through one device.

5 ORIGINAL IDEA Decide what aspect of home security that I want to focus on. Interfacing a keypad. Interfacing a different motor. Interfacing a snap-action switch.

6 PROBLEM STATEMENT Inputs Pushbuttons Toggle switches Snap-action switches What could you interface with the PLC, and it still be inexpensive. Outputs Lights Bells Motors

7 Get the hardware that I need to accomplish my goal, and wire it to the PLC. RESULTS

8 Write the software that I need to controls the inputs and outputs that I decided to use.

12 RESULTS A system that has an arming and disarming buttons. A switch that runs a motor to shut blinds and sets off a security light. A snap-action switch that runs a bell for an alarm.

13 CONCLUSIONS Found it was a realistic solution for a home security system. It can be wired and programmed easily.

14 FUTURE WORK Add a keypad for more security. Interfaced a better motor for my situation. Any questions???
