If the intruder passes without obstructing the laser it is considered as a failure.

Laser security alarm system circuit diagram.

Pull pin security alarm circuit. This is a project of smiple laser security alarm circuit. Laser security system a person moves in front of the sensor that person triggers the system s alarm by cutting the laser. And the alarm signals the security.

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. One of them can put in front of the locker while another one can be placed on the front door. If somebody tries to break the laser path then an alarm will be generated in a few seconds. If used with a battery the laser security system can work even when there is a power outage.

In this laser security alarm circuit we have used lm358 dual comparator ic for comparing voltages coming from ldr. Laser light circuit fig. Comparator is configured as non inverting mode and one 10k potentiometer is connected at its non inverting terminal. The circuit can be used as a laser door alarm laser motion detector laser proximity sensor or detector trip wire alarm and for other simple home security purposes.

The figure 8 shows the block diagram of 555 timer circuit 7 fo. Normally laser door alarm circuit will have two sections. The laser security system works only if the laser is obstructed. Working of security alarm circuit.

The circuit construction and setup for the laser security system is very simple. This circuit is con. Laser door alarm is based on the interruption of laser beam. As soon as you connect the battery the l e d and buzzer will come on if you re in a dark room.

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. R actual circuit refer to grebene 1984. Layout or path draw of the pcb fig 2. S1 and s2 are the two switches that are used in the circuit so that both can be put in two different places i e.

This video just to show how to make laser light security at home by using two transistor three resistance one photo resistance ldr and one led. Laser security system locks working along with circuit diagram. Your laser security alarm system is now ready. Sors and a basic alarm unit.

The laser pointer is used as the source of light beam.
