The IR Infrared Obstacle Avoidance Sensor Module is one of the most popular building blocks for beginner robotics in Pakistan. It uses a pair of infrared transmitter and receiver LEDs to detect any object in front of it and instantly outputs a digital HIGH/LOW signal to your Arduino — no complex code required.
Key Features
- Detects obstacles without touching them (reflective IR)
- On-board potentiometer to fine-tune detection distance (approx. 2–30 cm)
- Clean digital output — reads directly on any Arduino digital pin
- Power & output LED indicators for easy debugging
- 3.3V–5V operation, works with Arduino, ESP32, ESP8266 and Raspberry Pi
Specifications
| Working voltage | 3.3V – 5V DC |
| Detection range | 2 cm – 30 cm (adjustable) |
| Output | Digital (TTL) HIGH/LOW |
| Comparator | LM393 |
| Mounting | 2 fixing holes |
