In this tutorial I will show you how to make your own "Laser Security Alarm System" or a "Laser Sensor" on breadboard. This is similar to my previous video "Dark Sensor."
Its awesome once you complete the circuit and fun to play with. You can make this Laser Tripwire Alarm and protect your room from intruders :D You can even add multiple mirrors from different angles and focus it on the LDR for a greater effect.
COMPONENTS REQUIRED:- LDR, L.E.D, BC547 Transistor, 100k ohm resistor, 9v Battery, Buzzer & Breadboard.

If the people walk into the laser and it the alarm goes off, the people will know that there's a laser light security alarm system there so they will instantly back away and then they will try to run across it as fast as they can to make the buzzer goes off in as little time as possible. If the time the buzzer goes off is too short, it might not wake you up, you need a system where the buzzer goes off when someone walk into it and stay on forever until you turn it off.

Looks good but needs an alarm and it must stay on until it wakes you up and you must reset it and check if the intruder has gone please help to modify this thanks

Awesome. I am very new to electronics, not my profession (hobby). I have done your experiment and it turns on when it is dark. It only turned on when the obstacle was very close, practically touching the LDR. However the laser part did not seem to work since I have a laser pen like the one teachers use - maybe too weak, so I have reduced the resistance and it worked - hopefully I did not mess up something, but it worked like in your video.
