How To Make Laser Security Alarm Circuit Using Scr And Ldr Youtube Hello friends. welcome to the video. in this video, we will make a burglar alarm circuit using scr, ldr, resistor, capacitor, buzzer and laser.don't forget t. How to make laser security (theft) alarm using scr 1 km rangerequired components: 1) c106mg scr (silicon controlled rectifier)2) 680 ohm resistor3) 100uf 2.
How To Make Laser Security Theft Alarm Using Scr 1 Km Range Y Laser security (theft) alarm using scr 1 km rangerequired components: 1) c106mg scr (silicon controlled rectifier)2) 680 ohm resistor3) 100uf 25v capacitor. 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. All you need is an npn transistor, a resistor, a light dependent resistor (ldr), and an active 5v buzzer. this video shows you how to build it, and how it works. the video offers a theory lesson, and a lab build. i used a 10k ohm resistor, a 2n2222 npn transistor, a random ldr (most will work well with this circuit), and a 5v active buzzer. Step 7: connect battery clipper wire to the circuit. now solder battery clipper wire to the circuit as shown in the picture. solder ve wire of battery clipper to emmiter of transistor. and ve wire of battery clipper to ve of led.

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. The simple laser alarm circuit is a security system that uses a laser pointer and a light dependent resistor (ldr) to detect intrusions and trigger an alarm. the circuit is set up by pointing a laser beam across the area that needs to be protected, like a field or agricultural land. the ldr, placed at a specific point along the laser beam, is.
