Unit IR
SKU:U002
Description
Unit IR is a compact short-range photoelectric transceiver unit integrating both infrared transmission and reception. It features a 940nm infrared emitting diode and a 38kHz hardware-demodulating receiver, supporting modulated transmission and automatic demodulation reception for standard infrared protocols such as NEC. The unit communicates via a Grove HY2.0-4P interface with an effective range of less than 5 meters, and incorporates LEGO-compatible mounting holes for flexible integration with LEGO structures or screw-based installation. Suitable for smart home control, infrared remote learning, and short-range inter-device communication.
