[@omerbektas5713]

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

[@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.

Really good fun. We enjoy.

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

[@armantape]

preferably join a bistable flip-flop/multivibrator. so that the sound continues when the light is once blocked

[@shader26]

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.

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

[@sennopo289]

[@akinoye]

Yes

[@sube789]

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.

more of a toy than a serious project - very limited demo with no measurements whatsoever - no specs for the laser module - no suggestions on alignment - - construction is really terrible - - the SCR used is way overkill - LDR by itself is a poor choice as it is affected by ambient light-

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.

No it's not, it is because once the laser beam is interrupted, it constantly start buzzing till you press the reset button. And this is not how wanted. I want something like, it should make a buzz for second or two and then stop automatically...
