IR Obstacle Avoidance Sensor Module is an easy-to-use infrared proximity sensor designed for detecting obstacles or walls using IR reflection. It’s widely used in line-following robots, obstacle-avoidance vehicles, and automation projects where distance or edge detection is needed.
Key Features:
- Non-Contact Detection: Uses infrared light to detect nearby objects without physical contact.
- Adjustable Detection Range: Potentiometer allows tuning of sensitivity based on distance or material.
- Digital Output: Provides HIGH/LOW signal for easy interfacing with microcontrollers.
- Fast Response: Real-time obstacle detection ideal for mobile robotics.
- Compact and Lightweight: Small form factor suitable for tight embedded designs.
Technical Specifications:
- Operating Voltage: 3.3V to 5V DC
- Output Signal: Digital (LOW when obstacle detected)
- Detection Distance: 2cm to 30cm (adjustable)
- IR Wavelength: 850nm (infrared LED)
- Response Time: < 10ms
- Current Consumption: < 20mA
Mechanical Specifications:
- Dimensions: Approx. 48mm × 14mm × 8mm
- Mounting Hole: Single 3mm hole for easy panel or chassis mounting
- PCB Material: FR4, blue solder mask
Pinout and Wiring:
- VCC: Power supply (3.3V–5V)
- GND: Ground
- OUT: Digital output pin (LOW when obstacle is present)
Datasheet and Documentation:
