IR Infrared Obstacle Avoidance Sensor

Description

About this item:

• IR Infrared Obstacle Avoidance Sensor with four IR LEDs arranged around a central IR receiver — typically used in gesture recognition, obstacle detection, or proximity sensing applications.
• More specifically, it looks like a TCRT5000-based IR Reflective Sensor Array, or a custom IR proximity sensor module using photodiodes and IR LEDs.
• Specifications:
  • Operating Voltage: 3.3V to 5V DC
  • IR LEDs: 4 x 940 nm (typically)
  • Photodiode/Phototransistor: Centered between the IR LEDs (detects reflected IR light)
  • Output Type: Analog or Digital (depending on model and onboard circuitry)
  • Detection Range: 2–30 cm (varies with surface and ambient light)
  • Applications: Obstacle detection, robot navigation, gesture sensing
  • Mounting: 4 corner holes for easy mounting on robots or casings”
