IR LED Pair (Infrared Transmitter & Receiver)

The IR LED Pair consists of one infrared transmitter (black LED) and one infrared receiver (white LED), designed for use in infrared sensing and detection applications. This combination is widely used in electronics projects that require short-range object detection, motion sensing, and reflective surface detection.

The black IR LED (transmitter) emits invisible infrared light, while the white IR LED (receiver) detects reflected infrared signals from nearby objects or surfaces. Based on the received signal strength, the circuit can determine the presence, distance, or movement of an object.

This IR pair is commonly used in robotics, automation systems, and educational electronics projects due to its simplicity, low cost, and reliable performance. It can be easily integrated into breadboards, PCBs, and microcontroller-based circuits.

It is especially useful in applications where non-contact detection is required, such as obstacle sensing or line tracking, making it a popular choice for beginners and advanced developers alike.
