Circuit

A laser security alarm is a device that detects entry into a room or specific area using a beam detection system. This type of alarm is usually low-cost, simple, and reliable. To operate the device, a laser beam is directed from one point to another, and there is a receiver on the other side of the sensor that detects the laser beam. If a detection occurs, the receiver triggers the circuit, which then sets off an alarm.

In this project, we will make a laser security alarm using an SCR (Silicon-Controlled Rectifier). The SCR allows current to flow when it receives a triggering signal. In this project, a triggering signal will be created when the laser beam is interrupted, and the SCR will be triggered. This will activate the alarm circuit, which will sound an alarm.

For detailed instructions on this project, you can check out the YouTube video titled "DIY Laser Security System with Alarm Using SCR." The video covers all the necessary materials, circuit diagram, assembly steps, and finally, testing the device.

This project can be a simple yet effective security system for your home or workplace. However, like any security system, it is recommended to combine this laser security alarm with a series of security measures.

zafer bey birde alarm sisteminde kullanılan pır veya fotoselli lambaları gözlerini kullanarak yüksek sesli alarm devresi yaparsanız çok iyi olur

Bom dia parabens muito bom excelente projeto

The description says 1 km, but that's impossible. There are too many disturbances in the air. A single bird or bee or even fog could trigger it. Even at 30 meters, there is a good chance that something small might trigger it. If this laser beam alarm must trigger only on large animals or humans, then it should have 2 or more CdS photocells and they should trigger only when both beams are blocked by a large animal or human. Another problem is the beam can be seen, so a human can avoid it and get through without triggering it. An Infrared beam would be harder to see. Or instead, buy a PIR sensor like the ones used on security lights.
Thanks for the good project. It's difficult to watch a short video and build one of these because the video doesn't give enough time to see the parts.

Хороший макет устройства, качественная пайка, но до реального применения ещё далеко. Когда будет законченное устройство?

Zafer bey, sayenizde işime yarasın/yaramasın bir sürü cihaz yaptım. Şikayetim yok, teşekkür ediyorum. Benim gerçekten merak ettiğim ve bir çok abonenizin de beğeneceği bir cihazı merak ediyorum. Kanatsız fan ve bununla yapılan itici ventiller. Bu konuda bize bir video hazırlayabilir misiniz?
