Infrared Transmitting And Receiving Module The module supports 38 kHz carrier infrared signal transmission. The receiving module contains four infrared transmitting tubes. It can also receive instructions from other infrared remote controls and perform corresponding actions. By cooperating with a microcontroller, it can emit infrared commands to control electronic products such as air conditioners, fans, and other devices. Arranged at the four corners of the module, it achieves 360° infrared signal transmission without blind spots. Applications and use scenarios Home automation and device control: integrate with a microcontroller to emit IR commands and control air conditioners, fans, and other electronic products. Remote control extension and integration: receive signals from existing remotes and trigger actions through your MCU driven system. Prototyping and education: use as a practical IR transmitter/receiver platform to learn about IR protocols and MCUbased control. Key attributes Function: bidirectional capability (transmit and receive) with 38 kHz IR signaling. Compatibility: designed to work with standard IR remotes and microcontrollerbased control systems. Coverage: fourcorner arrangement provides wide 360° signal transmission. Performance: enables emission of IR commands to control common household electronic products when used with appropriate microcontroller logic.
