Laser Alarm Security System Electronics Project Circuit Working

Laser Alarm Security System Electronics Project Circuit Working 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. 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.

Laser Security Alarm Circuit 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. Laser security system working the working of the circuit is simply based on a voltage divider circuit. as the light intensity on ldr increases its resistance decreases, so when laser light is falling on ldr, its resistance goes very low hence the 9volt supply gets connected to the ground with the help of a 10k resistor, and in this way base of. Working of the laser light security system using arduino. 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 push button. the laser is a concentrated light source that puts out a straight beam of light of a single color. The laser light security system using 555 timer operates by monitoring the presence of a continuous laser beam. at the heart of the circuit is a 555 timer ic, configured in monostable mode, which responds to changes in light levels detected by the light dependent resistor (ldr). a laser pointer or laser diode module is used to provide a steady.
