1.     Power Supply

2.     Resistors of 100Ω, 220Ω & 10K

3.     LDR

4.     Buzzer

5.     Laser Diode

6.     Transistor NPN

7.     Connecting Wires

 

Circuit Diagram:


Connection Procedure:


Laser Transmitter Circuit:


Step 1: Take a Laser Diode and place it on KIT Board by Connecting the anode of the Laser Diode to (Pin 86) and the cathode to (Pin 84).

Step 2: Connect the positive terminal (Pin 63) of the Power Supply to one end of the 220Ω resistor (Pin 3).

Step 3: Connect the other end of the 220Ω resistor (Pin 4) to the anode (Pin 85) of the Laser Diode.

Step 4: Connect the cathode (Pin 83) of the Laser Diode to the negative terminal (Pin 60) of the Power Supply.


Laser Receiver Circuit:

Step 5: Connect the positive terminal (Pin 62) of the Power Supply to the positive terminal of the Buzzer (Pin 54).

Step 6: Connect the negative terminal of the Buzzer (Pin 53) to one end of the 100Ω resistor (Pin 1).

Step 7: Connect the other end of the 100Ω resistor (Pin 2) to the collector (Pin 31) of the NPN Transistor.

Step 8: Connect the positive terminal (Pin 62) of the Power Supply to one end of the 10K resistor (Pin 11).

Step 9: Connect the other end of the 10K resistor (Pin 12) to both the base (Pin 30) of the NPN Transistor and one end of the LDR (Pin 80).

Step 10: Connect the negative terminal (Pin 59) of the Power Supply to the other end of the LDR (Pin 79) and also to the emitter (Pin 29) of the NPN Transistor.

 

To test the project's intrusion detection capability, simply interrupt the laser beam with an object or your hand and observe if the alarm is triggered.


Explanation:

In this project, we'll explore a laser security alarm. This system uses a laser beam to detect intruders by sensing the reflection of the beam. Components like a laser diode, LED, buzzer, and others are connected in a circuit. When an intruder interrupts the laser beam, the system triggers an alarm. By analyzing the reflected beam, the system can determine characteristics like distance, size, and speed of the intruder, helping to differentiate it from other objects.

RFID Door Lock Using Arduino Uno(Automation Project )

The RFID Door Lock system is a secure and convenient access control solution that uses RFID technology to allow or deny access to a door. By scanning an RFID card, the system can identify authorized users and trigger a servo motor to unlock the door if access is granted. This technology is widely used in offices, homes, and restricted areas to ensure only authorized personnel can enter.
