Features:

• Infrared TX/RX pair for reflection detection
• Adjustable sensitivity via onboard pot
• Digital output (LOW on detect)
• Dual LEDs: red power, green obstacle
• 3-wire interface (VCC, GND, OUT)
• Direct relay drive (5V)
• Wide 35° detection angle
• IR obstacle avoidance sensor – the tiny infrared eye that keeps your robot from crashing into walls! This IR obstacle avoidance sensor shoots 38kHz IR beams, detects reflections from 2-30cm away, and screams “STOP!” via digital LOW on the OUT pin.
• Compact 3-wire module (VCC, GND, OUT) with red power LED + green detect LED. Twist the blue pot for perfect sensitivity – ignore crumbs, spot bricks. 35° wide beam catches obstacles left-to-right. Drives 5V relays directly or feeds Arduino digitalRead() for instant alerts.
• Why 50,000+ Indian makers (now in BD) swear by this IR obstacle avoidance sensor:
  ✔ Adjustable detection: 2cm (close-up) to 30cm (hallway scan)
  ✔ Low-power IR pair: <20mA, runs on 3-5V batteries
  ✔ No false triggers on black/white lines (great for dual use with trackers)
  ✔ Pre-soldered headers + bonus 3-pin cable
• Build smart cars, maze solvers, anti-fall alarms, or door sensors. Pair with HC-SR04 for ultimate robot vision.

FAQ

1. How does IR obstacle avoidance sensor work?
   IR LED emits 38kHz beam. Photodiode catches reflection from obstacle. LM393 comparator flips OUT to LOW if signal > threshold (set by pot).
2. What is the exact detection range?
   Factory: 2-10cm. Twist blue pot clockwise for up to 30cm. Test with white paper (reflects best).
3. Can I use it for line following too?
   Yes! Mount upside-down over track. Black line absorbs IR (no reflection = HIGH), white reflects (LOW).
4. Arduino connection?
   VCC→5V, GND→GND, OUT→Digital Pin 2. Code: if(digitalRead(2)==LOW) { stopMotor(); }
5. Why green LED blinks randomly?
   Weak reflection (dark surface). Adjust pot counterclockwise for stricter threshold.
6. Works on 3.3V ESP32?
   Yes – VCC to 3.3V. Output is 3.3V logic safe.
7. False positives from sunlight?
   Indoor only. Sun floods IR spectrum. Use indoors or add IR filter (not included).
8. Can it drive a buzzer directly?
   Yes – OUT LOW sinks 20mA. Connect buzzer + to 5V, – to OUT.
9. Difference from TCRT5000?
   This is reflection-based (obstacles). TCRT is transmissive (line breaks).
10. Mod for analog output?
    Solder wire to photodiode pad. Read via analogRead() for distance estimate.
