How to make Laser Security Alarm System without LDR || Inspire Award project || SKR Electronics Lab

Hello everyone, and welcome to our channel! In this video, we'll guide you through the process of creating a Laser Security Alarm System without using an LDR sensor. Instead, we'll utilize a regular diode as a light-sensitive component to detect changes in the laser beam.
For this project, you'll need the following components:
⦿ Diode
⦿ Two BC547 NPN transistors
⦿ One 1M resistor
⦿ 5V buzzer
⦿ 3.7V battery
⦿ Push on-off switch
🔘Here's how it works:
By using the diode as a light-sensitive component, we can detect changes in the intensity of the laser beam. When an object obstructs the laser beam, the amount of light reaching the diode changes, altering its electrical characteristics. This change in electrical properties is then amplified by the two BC547 NPN transistors, which activate the 5V buzzer to sound the alarm.
The 1M resistor plays a crucial role in maintaining stability and ensuring proper functionality of the circuit. It helps in maintaining the balance of the system and provides the required resistance for accurate detection.
With the push on-off switch, you have convenient control over the system's activation, allowing you to easily turn the laser security alarm on or off as needed.
Our step-by-step instructions will walk you through the entire process of building this laser security alarm system using a diode as an LDR sensor. Whether you're a beginner or an electronics enthusiast, this project offers an exciting opportunity to enhance your understanding of light detection and security systems.
So gather your components, follow along with our instructions, and create your very own laser security alarm system using a diode as an LDR sensor. Let's get started!

Nice 👍

[@YaduvanshiAyush-ot2ri]

Very nice

[@dilipsahu4909]

I am trying, but it's not working

[@toxic_sanatani0]

Yes i am also trying but it's not work

[@sazadur_rahman]

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

[@skr_electronics_lab]

Active and the Operating Voltage is 3v to 5v

Not working

[@upendraprajapati1658]

I am trying not working

[@skr_electronics_lab]

Break the the diode carefully

[@IcoN_Yt_]

Bhai ye sach me kam karega kya please reply😢😢😢😢😢😢

[@rafikulislam5598]

Aap register
Kahan per baithe ho

[@upendraprajapati1658]

Continue Alarm bajta rahta

[@skr_electronics_lab]

Bro ap acche se diode ko break nahi kr pa rehe ho islye asa ho raha hai

[@MDSojibIslam-kt4uf]

This is Fake video

[@skr_electronics_lab]

Proof krke TH-cam pr upload kro ki yewah fake hai and mujhe tag kro fir me yah video delete kr dunga 😊
