OBJECTIVE ;-Burglar alarms are automatic home monitoring devices to monitor and alert in case of a burglary attempt at that place – house or a commercial place.

Our objective is to ensure security of property using our device.

COMPONENTS ;-

BC 547 Transistor 100k Ω & 100 Ω Buzzer LED

LDR 9 V battery with snap Connecting wires GPB

CIRCUIT DIAGRAM ;-

WORKING OF LASER INTRUDER/BURGLAR ALARM CIRCUIT :-

This circuit alarms whenever someone cross the Laser beam transmitted from a LASER.The output of Transistor goes high whenever their is no Light(Laser) Ray. This output voltage is further amplified by means of a NPN transistor, which will drive the buzzer and generates an alarm.

PRACTICAL CIRCUIT ;-

APPLICATIONS ;-

CONCLUSION ;-

Home security is rapidly growing field and there are new & improved burglar alarms popping up everyday.

With rapid advancement of technology the filled is turning out to be an area full of scope and new changes can be made to make it’s more efficient.

It has years to come, because security is of prime importance to one and all.
