01 — About

What it does

The IR LED Pair consists of an infrared LED transmitter and matching photodiode receiver. Together they form a simple IR proximity sensor or beam-break detector for line following, object detection, and counting applications.

Key features

  • IR transmitter + receiver pair
  • 940nm wavelength
  • Simple proximity detection
  • Beam-break capable
  • Low cost
  • 5V operation

Good to know

  • LED and photodiode must be aimed at same point
  • Ambient IR (sunlight) affects performance
  • Use modulated IR (38kHz) to reduce interference
  • Shield from external light sources
  • Adjust LED current for desired range
