Abstract:
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.
