PCB DESIGN IR MODULE

INTRODUCTION :-

An IR (infrared) sensor module is widely used for object detection,obstacle avoidance,and Automation System.in this project we design a compact PCB for IR module using kicad.

This PCB makes the circuit make more reliable ,compact,and easy to use in real world application like robot and samart system.

SUPPLIES:-

1. IR LED(Transimitter)
2. Photodiode/IR receiver
3. comparator IC(LM358)
4. Resistor (100k)
5. preset (10k potentiometer)
6. LED (indicator)
7. jumper wire
8. software(kicad)

WORKING:-

The IR LED emit infrared light when i objects come near ,the IR light reflect back and it is detected by the photodiode.

The comparator IC(LM358) processes the single and give low output.

1. object detected - output low
2. No object-output opposite

CREAT SCHEMATIC

STEP1:-

1. Open Kicad
2. Create new project
3. Add Component(Press A or direct the screen button)
4. connector pin 1*3 male
5. power(5v)
6. GND
7. IR LED
8. photodiode
9. LM358 IC
10. Resistor +Preset
11. Connect all component(for connection press W) as per image
12. Annotate schematic(for nameing every component)

ASSIGN FOOTPRINT:-

1. Go to assign footprint or simply press "F" any components select the footprint.
2. And also select footprint in assigne footprint option as shown in image

Step4:-

1. Go to Tool
2. Select "Update PCB from Schamatic " (it covert schamatic into PCB)
3. After select we see option "Update PCB " select this option.
4. Then we see all the components Place the components properly.
5. select rectangle
6. Draw rectange place all component properly into the rectangle.
7. Rout Track
8. Use Thicker Track for vcc and GND .
9. Thin Track for signal.

FILL ZONE:-

1. select the fill zone as shown in image.
2. choose the GND.
3. Click PCB boundray
4. This reduce noise and improve performance

3D VIEW:-

1. press Alt +3 in kicad
2. Check:
3. check component palcement.
4. And PCB shape

APPLICATION:-

1. Obstacle avoiding robot
2. Line follower robot
3. Automatic Door system
4. Object Counter

CONCLUSION:-

Designing PCB for IR module improve realiability and makes your project look professional .Once fabricated,it can be directly used in robotic and automaion system.
