Simple Laser Security Alarm Circuit Diagram. This is a project of smiple laser security alarm circuit. Your laser security alarm system is now ready.
The proposed foolproof laser security circuit can be witnessed in the following diagram. Two npn bc548 transistors implemented in this security alarm circuit as a switching device. Previously we have also built some security alarm circuits like this pir sensor based motion detector and burglar alarm circuit.
Simple laser security alarm circuit diagram.
Two npn bc548 transistors implemented in this security alarm circuit as a switching device. In the earlier article we saw a rather simple laser controlled burglar alarm circuit where the alarm is sounded whenever the laser beam incident on the ldr is interrupted. The circuit can be used as a laser door alarm laser motion detector laser proximity sensor trip wire alarm and for other simple home security purposes. Two npn bc548 transistors implemented in this security alarm circuit as a switching device.
