and how they work.
Components Used:
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.
