Abstract:
The need for security cannot be overemphasized in today’s modern world, where theft, causes
much damages to the institutions and lead them to loss, so that is why I developed the security
system entitled Intercommunication for security service within an institution with the help of
passive infrared ultrasonic sensor for detecting Objects, GSM SIM900 for sending the
message to the person in charge of security, ARDUINO UNO, LCD for displaying the situation,
and the buzzer for alarming. It is the project which will be used anywhere for safety, as some
institutions has the private places where people are not allowed to go for examples in medical
research laboratories they have the place where they keep their researches and they don’t need
anyone to go there, so they can use my project to keep the place safe. Because my project is able
to display the message telling people that it is not allowed to come close by, it is able to detect
the movement where it is not allowed, it is able to alarm giving the person close by to stop and
even alarming the person in charge that someone is close, it also have the global system for
mobile (GSM) system to send the sms to the person in charge wherever they are. The system
resulted in a cost saving, smart, portable and a more efficient way of implementing
Intercommunication for security service within an institution.
