Home Security System


Introduction
This is a digital home security system with voice feature which can monitor room temperature, smoke, motion, and windows & doors.

The goal of this project is to utilize the after-market parts and build an integrated home security system. Besides traditional magnetic switch equipped on doors and windows, we have also incorporated temperature sensor, smoke detectors, and motion sensor. Hence the security system will sound an alert when there is an attempt of break-in or if there is possible smoke or fire.

The system is fully digital and also be fully customized. It incorporated a 16x2 LCD display with a 4x4 keypad. Each sensor can be enabled or disabled, and alarm frequency and skim can also be chosen by users. We have also equipped a voice playback chip, and it will speak which sensor has gone wrong.



High Level Design
Project Idea
The idea of our project comes from lab 3 when we did a simple security system. However, that security system is quite basic and only offers simple password lock. Hence we would like to enhance our security system with different kinds of sensors. We have also browse some of the old final project and found the "Phone Dialer" project from spring 2002. Originally, we were going to put Zarlink MT8880C DTMF transceiver chip, so it will dial a desire number that user specify. When the phone connected, we will use Winbond ISD1420 voice record and playback chip to play pre-recorded voice signal. However, due to the lack of the phone jack in the lab, plus the majority of the Cornell campus has digital phone line instead of analog phone line, we decided to put away this idea. Since ISD1420 chip has address bit feature, we decided to make our system playback certain pattern of voice when the system goes into alert status.
