38+ Laser Light Security Alarm System Background. In this project, we will discuss home security alarm using pir sensor & arduino. Focus the laser diode/light on the ldr and you will see the l.e.d and buzzer going off if you interrupt the laser light focusing on the ldr the circuit will trigger and the alarm will ring!
You can use this project to protect your house, shop and other things. Laser light security alarm are functionally designed to ensure that they fit correctly in the intended spot. A maximus security light does something surprising:
Working of the laser light security system using arduino.
Laser based security system is a type of security and alarm system that uses laser light and a light sensor. Hi friends, in this video i will show you how to make a laser light security alarm system at home easily. Laser light security alarm are functionally designed to ensure that they fit correctly in the intended spot. In this laser security alarm circuit we have used lm358 dual comparator ic for comparing voltages coming from ldr.
