Infrared Transmitting And Receiving Module Key features 38 kHz carrier infrared signal transmission for standard remote control compatibility. Receiving module includes four infrared emitting diodes arranged at the four corners, providing 360° coverage with no blind spots. When used with a microcontroller, can emit infrared commands to control electronic products such as air conditioners, fans, and other compatible devices. Can also receive commands from other infrared remote controls and trigger corresponding actions. Benefits and capabilities Reliable, wideangle IR transmission with four corner emitters reduces dead zones and improves control reliability. Dual role support (transmit and receive) enables simple integration into automated or learningbased projects. Flexible compatibility with microcontrollerbased systems, facilitating custom control solutions for common household appliances. Clear alignment with standard 38 kHz IR signaling ensures broad interoperability with existing remotes and devices. Applications and use scenarios Smart home control hub: integrate with a microcontroller to issue IR commands for air conditioners, fans, and similar devices, enabling centralized or automated HVAC and comfort management. IR signal extender or repeater project: use the module to extend remote control coverage within a room or between rooms, simplifying multiarea operation of household electronics. DIY IR learning and reproduction: connect to a microcontroller to learn commands from existing remotes and reproduce them for customized control schemes or macro programs. Notes on use Designed to work in projects that require both sending and receiving IR signals, leveraging a 38 kHz carrier for compatibility with common consumer electronics. Suitable for embedded system integrations where compact, discrete IR transmission and reception are needed.
