Laser Security Alarm Project How To Make A Laser Light Securi A laser based security system is a type of security alarm that uses a light sensor and laser light. in this tutorial, we are going to demonstrate a circuit of a laser security alarm system that will detect any irregular activity and will produce sound using a buzzer. one of the main components of this circuit is ldr. In this video i am going to show you how to make a laser light security alarm system.what you need to build this project bc547 transistor amzn.to 3gv.
How To Make A Laser Light Security Alarm Youtube Step 4: testing the security system. the project basically works on the principle of interruption. if by any means the laser light is interrupted the alarm will start unless it is reset with the pushbutton. the laser is a concentrated light source that puts out a straight beam of light of a single color. the ldr is sensitive to light and puts. In this project, we have designed laser light security system using arduino with alarm with the application of laser diode module ky 008. the project idea revolves around creating a security system. whenever any object will obstruct the laser ray the buzzer alarm will start ringing. this project can be implemented anywhere, not only buildings. Step 1: how it works. when the laser pen shines on the photoresistor, the green led will light up to signify that the circuit is ready. when the laser beam is broken, the led turns off and the buzzer sounds. as we know from projects 13 (“weather station”) and 18 (“intruder sensor”), photoresistors produce variable resistance depending. This system uses a laser beam and an ldr sensor to detect any changes in the light level and triggers an alarm if someone enters the protected area and interrupts the laser beam. with the ability to adjust the threshold value and customize the system to fit specific needs, this type of security system can provide reliable protection for homes.

Fig. 1: layout or path draw of the pcb fig.2: laser light circuit fig. 3: schematic circuit diagram of the laser light security alarm system step 2. clean the pcb with the help of a scrubber and after taking a small size container and some pcb etching solution (ferrous chloride), prepare a solution of etching by mixing the ferrous chloride and water in a container. Steps: connect the ldr sensor to the breadboard. connect the 220 ohm resistor to the ldr sensor and connect it to the ground pin on the arduino board. connect the buzzer to the breadboard and connect the positive pin to pin 8 on the arduino board. connect the laser diode to the breadboard and connect the positive pin to pin 2 on the arduino board.
