Unit IR
SKU:U002
Description
Unit IR is a short-range photoelectric paired-tube unit that integrates infrared transmitting and receiving functions. It uses a 940 nm infrared emitting diode and a 38 kHz hardware-demodulated receiver, supporting modulated transmission and automatic demodulation reception of standard infrared protocols such as NEC. The unit communicates via a Grove HY2.0-4P interface, with an effective communication distance of less than 5 m. It features LEGO-compatible mounting holes, making it easy to integrate with LEGO structures or secure with screws. It is suitable for applications such as smart home control, infrared remote learning, and short-range communication between devices.
