MICROCONTROLLER DETECTION SYSTEM

Joshua BosiljevacEKU

MOTIVATION● Simple detection system you can place

anywhere● Continuation of a project from a previous

class

PROBLEM STATEMENT You want to monitor the front

or back door for whether an intruder has entered while you are busy upstairs

You won't always be able to hear what is downstairs

Assumptions A few assumptions could be

that you can mount it where it can not be disabled easily.

You have a easily accessible power source for it to operate

PROPOSED SOLUTION Detecting a RFID for a door Switch detecting whether the door

is open Determining whether it was open

with or without a correct rfid

Result

● When an authorized rfid is scanned green LED is turned on

● When an unauthorized rfid is scanned red LED is turned on

● If the door is open without authorization the yellow LED is turned on

● If the door is left open for 5 seconds after authorized user scans it will turn on the yellow LED as well

CONCLUSIONS This is the basic for detecting

some sort of intrusion Adding ability to set off alarms

and trigger locks would require a few additions

FUTURE WORK Simple detection system This can be used as a base of an

actual system to control locks and alarms

ACKNOWLEDGEMENTS Vigs for core components of

project
