Abstract:
This is the age of modern science. The advanced technology makes our life easier and also
negatively affected our life such as increasing the crime rate. So people are trying to keep
themselves save. To keep save themselves and their family, they want to make their home is the
safest place ever. Day by day, people develop their home security system. There are so many
security systems which are developed in various ways. Security is an important issue of all time.
That is why we choose advance home security system as our final year project. This paper
proposes the development of GSM and Laser Based Home Security system. The main scheme is
to develop a system based on Arduino that is providing a full security system of home by
alarming against undesired things as well as notifying via sms through mobile services when we
stay outside of home. The system basically consists of Arduino, GSM module, LDR, LASER,
and Buzzer to ensure the safety system both home and industries. If there are any undesired
things around our home or industry, the system will notify us by alarming and via sms. It is
worked by sensing any obstacle in LASER path.If there is any substance between LDR and
LASER, the LASER breaks and LDR sense no LASER. Then it gives a signal to
Arduino,Arduino analysis the problem and gives an amplified signal to Buzzer which alerts the
user. In the meantime it also sends an alert message to the user by GSM module for extra
security. The whole system isArduino dependent and it is controlled by Arduino programming.
The main objective of this system is to ensure the safety system by Arduino programming which
gives safety from any unwanted situation and as well as alert people by sending an SMS.
