How to make Laser Security (Theft) Alarm using SCR - 1 KM Range

[@paparoysworkshop]

One kilometer range? Good luck with that. When I was a kid, I built a similar circuit that would switch a relay on when the beam was interrupted, and off again when interrupted a second time. I placed this across my bedroom door so when I entered my bedroom, the lights automatically came on, and when I left, the lights would shut off. It didn't take long for my sisters to realize they could place their hand through the beam then run away leaving me in the dark.

[@ShivaShankar-rj4rg]

Really good fun. We enjoy.

[@Sgt.Rafael-kl8bu]

You try this and it works?

[@milankumar1835]

Can you make a video on it or send a circuit diagram

Indeed. Many obstacles can cut this circuit out.

years ago, I applied this for the security of a large area, I circulated the laser in the desired routes through small mirrors.

These build types (no perfboard, just component to component) always amaze me, and I have respect for the folk that show this. I do notice that their soldering irons are always in bad shape. I mean terrible. But I am impressed with the rest of it. Notice sometimes they cut away and have added solder. Not surprising.

Ist great! thanks, input voltage? is 5v? and power for the lazer? the bat is 1,5v or 3.7v too

use a capacitor in series with the buzzer. 100 k resistor parallel to the capacitor. then after 1 minute sound will die. again after little time it is ready to detect. change the values until you are happy.

However, It's just a demo version which may cover 1 square feet that doesn't matter though at all. Anyway, it's good though for security purposes with home made laser light services. Without doubt, it's definitely Praise worthy Good Job 👍. Of course, this person at least deserves appreciation for his invention by making this type of home made security gadget.

Buddy, plz dont write comments like this before using your brain! You're just embarrassing yourself...what it meant is, the distance is dependent on the laser that will be used. There are many lasers out there tht can shine straight beams for long distance.

If you want to extend its distance then you can use optical fiber cables as per your need…

[@ruddy3962]

on the left side of the circuit (input side) , what have you used as input? does 9 V battery works?

If you are using 5 volt Buzzer then you should use 5 volt power supply.

[@rakshith9584]

Problem :The reset button is not working, when the light is blocked the buzzer beeps and when the object passes away it resets on its own without the use of the reset button

[@CG-rr6yx]

C106MG is a thyristor ( = SCR ), not a transistor. Working in direct current, it latches in the ON position until the current is interrupted. An electromagnetic buzzer indeed would interrupt the current at every oscillation. The buzzer used in the video is an electronic one and it absorbs current continuously, thus it remains ON until the reset button is pressed .

[@NIKOSAUDIO1409888888]

Hello if I don't put the buzzer can I use the 5 volt out to send this command to activate a contactor to activate a external siren?

[@SheikhAzmat-i2g]

You can use these two points to actuate anything but through a relay contact.These two points will energize a relay, the relay contacts can further run/actuate anything.Thanks from Pakistan.

[@neetusharma1274]

Personally I feel that very high precision is required to fix laser on LDR,and highly qualified,(usually uneducated)people who do such kind of things can easily break through.

Height of the object matters a lot here. If someone jumps over or under the laser line, it may not detect. Multiple laser beams at various levels would possibly help.

[@sube789]

you have to use 2 of them with an AND gate. Other vise insects will ring the alarm. But using a PIR is easier.

[@MrXyzasdf]

I was thinking the same but I think we can use a PIR sensor to trigger the secondary laser circuit and then maybe setup some fuzzy logic to monitor the dwell of the PIR and laser to accurately eliminate false alarms.
