Laser security system locks working along with circuit diagram.

Laser security alarm system circuit diagram. Layout or path draw of the pcb fig 2. The figure 8 shows the block diagram of 555 timer circuit 7 fo. Pull pin security alarm circuit. This is a project of smiple laser security alarm circuit.

The laser security system works only if the laser is obstructed. Hi i made a laser security system with resistors 1k and 6 8k and fet. The laser pointer is used as the source of light beam. 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.

Your laser security alarm system is now ready. Laser door alarm is based on the interruption of laser beam. If somebody tries to break the laser path then an alarm will be generated in a few seconds. Working of security alarm circuit.

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. Comparator is configured as non inverting mode and one 10k potentiometer is connected at its non inverting terminal. If used with a battery the laser security system can work even when there is a power outage. Normally laser door alarm circuit will have two sections.

Circuit diagram and explanation. Laser light circuit fig. R actual circuit refer to grebene 1984. One of them can put in front of the locker while another one can be placed on the front door.

If the intruder passes without obstructing the laser it is considered as a failure. 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. Laser security system a person moves in front of the sensor that person triggers the system s alarm by cutting the laser.

Easy laser light security system circuit at home. In this laser security alarm circuit we have used lm358 dual comparator ic for comparing voltages coming from ldr. Sors and a basic alarm unit. 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.
