The door alarm opening circuit is used for alerting you when a customer is at your office or shop. It will produce a beep sound when each customer or visitor is entering, and will automatically switch OFF after few seconds.ResultsIt automatically operates by opening the door.It gives a beep sound alert.Easy to install.limitationsNo means of informing the homeowner/user of an ongoing threat in his/her house.There could be a possibility of an intrusion without the intruder opening the door and channel his/her through other means.

EXCELLENCE IN TECHNOLOGY EDUCATION7

This is the circuit of a simple burglar alarm that produces a loud beep when somebody crosses the area or door. It is used for protection against intruder by sensing a shadow movement from a distance. When somebody approaches the unit it will produce a loud alarm to abort the attempt of theft.ResultsThe sensor is very sensitive.The circuit is easy and cheap to put together.limitationsBased on this particular project, we realized that the probability of having false alarm is high due to the high sensitivity of the sensor. We also noticed that this particular system caters only for burglar/intruder detection system by signaling an audible alarm. This system has no means of personally informing the user by sending an SMS when he/she is not at home to its multiple users should incase ones phone is off.

The system has two main parts; an intruder sensor cum transmitter and a receiver. The intruder sensor reacts to light, sound and mechanical movements. When the sensor detects a disturbance, the transmitter gets triggered and begins to send wireless signals. The receiver placed away from the transmitter receives the signals and produces an audio alarm.ResultsThe distance between the receiver and transmitter could be very long.Limitations Based on this particular project, this system has no means of personally informing the user of any ongoing security threat by sending an SMS/information to multiple numbers even if the phone is off or when he/she is not at home. Also the use of a wireless receiver and transmitter brings about problems due to frequency allocation.

Costly design. It has no means of informing the homeowner/user of an ongoing threat when he/she is not at home. We intend to solve these problems by adopting the techniques with the implementation of smart alarming features that is also able to inform homeowner/user of an ongoing threat by sending an SMS to multiple users should incase ones phone is off; opted into the security system.
