It is hard to keep house in a very safe conditions, window is one of the easiest ways for intruder to break in as the window is breakable. Other than that, lack of neighborhood’s attention without an alarm system is another problem occurred. If there is a break in, the owner did not get alerted unless someone called them.
The purpose of this Intruder Alarm System with GSM is to sense the presence of movements in front of the ultrasonic sensor with the LED and piezo buzzer is being turned on and the GSM sending information (SMS) to owner's phone number. So it can be used to prevent the burglar to break into the house without owner's presence. It is also useful to prevent the house property from being stolen by the intruder.
