Home Security System

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 16×2 LCD display with a 4×4 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.
