Layout or path draw of the pcb fig 2. Comparator is configured as non inverting mode and one 10k potentiometer is connected at its non inverting terminal. T2 bc558 1. Laser security system circuit diagram and explanation in this laser security alarm circuit we have used lm358 dual comparator ic for comparing voltages coming from ldr. Resistors are the passive device with two terminals. S1 s2 2. Below is a circuit design diagram which illustrates the flow of a laser alarm system. Schematic circuit diagram of the laser light security alarm system step 2. Ldr light dependent resistor connected to the base terminal of q2 transistor through r4 resistor this ldr gives low resistance when the laser light falls on it and gives high resistance when there. The circuit is using only few low cost components.
Place the bc547 transistor on the breadboard as shown in the fig below.
An ldr photo resistor is used to sense the laser beam. 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. Laser light circuit fig. Layout or path draw of the pcb fig 2. S1 s2 2. R3 1 2k 1.
Then connect the ldr from the base and emitter of the bc547 transistor. Comparator is configured as non inverting mode and one 10k potentiometer is connected at its non inverting terminal. When any person or object will come in between the laser beam the laser beam will be cut or interrupted therefore the ldr will not sense beam on its surface that increases the. In this video i explained that how the laser light security alarm circuit. S1 s2 2. They are mainly used in the circuit to restrict the flow of current across any of the. R4 47e 1. The circuit is divided in to two sections first is a laser transmitter or laser light and second is a laser receiver with time delay and alarm or siren circuit. Layout or path draw of the pcb fig 2.
