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.

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

Пять с половиной минут смотрели как надо паять. Гениально. Наверное целый год думали над этой схемой!

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.

Highlight of the video @4:20 no annoying music.

This does NOT have 1000 meters range. This is useful over 1 to 5 meters, that's all. CLICKBAIT.

Music will not give any positive result.explane details.

What's the Buzzer model? Is it active or passive? What's the operating voltage? plz mention.

Cool - nur das einzige Problem aktuell ist, das es kaum noch Läden für diese Bauteile gibt..

Классный датчик периметра можно соорудить.

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.

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

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

[tmsunderrajan]

Hahaha!
I am an hobby electronic person. Now I am 70+ and recently found that my hands shake while doing soldering. However after watching this video, which I suppose must be created by an young person, I feel I am not that bad.
Thanks.

Sir you are a expert in this field I have a question for you

[mustafadelmonte]

Wow thats a nice idea.. but considering the insect and bugs that interupt the laser.. you will never have a night sleep. And in 1km distance the pointer of your laser will be the size of umbrella.😂 garage park assist is better than security bro.

[LEdiablo]

Instead of a on/off switch button, is it possible to put a timer (like 30 seconds) ?

[chinmoy]

How long do you think this LDR will last with the laser beam falling on it's surface constantly???🤔

[zjyeofi]

До 5метров и это хорошо. Свыше как я понимаю нужна оптика, центровка. Благодарю!

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
