IR Proximity Sensor with SMD UNO Compatible with Arduino

What this module actually is

This is a combo package that includes:

• Arduino UNO SMD board (ATmega328P)

• IR Proximity Sensor module

So instead of buying separately, you get both together.

Arduino UNO (SMD Version)

• Microcontroller: ATmega328P

• 14 digital pins + 6 analog inputs

• Clock: 16 MHz

• USB interface (CH340 chip in many versions)

Difference from normal UNO:

• Uses SMD (surface-mounted) chip instead of removable DIP

• Cheaper but functionally the same

IR Proximity Sensor (included)

• Detects objects using infrared reflection

• Range: ~2 cm to 30 cmHIGH/LOW)

• Comparator IC: LM393

• Adjustable sensitivity via potentiometer

How it works

• IR LED emits invisible light

• Object reflects light

• Receiver detects reflection

• Output changes Arduino reads it

Output is usually LOW when object detected

Wiring (very simple)

Applications

• Obstacle avoiding robot

• Smart car

• Object detection

• Automatic door

• Line follower

Imp Affected by sunlight and black objects

Not for accurate distance measurement

Needs adjustment via potentiometer

Why choose this combo?

Pros

• Everything in one kit (beginner-friendly)

• No need to buy Arduino separately

• Plug-and-play learning

Cons

• Slightly costlier than buying separately

• Less flexibility in choosing components

Final Understanding

This is NOT a special new sensor It's simply:

• Arduino UNO (SMD version)

• • standard IR obstacle sensor
