Infrared Transmitting And Receiving Module Key features Supports 38 kHz carrier infrared signal transmission Receiving module contains four infrared transmitting tubes Four tubes are arranged at the four corners of the module, enabling 360° infrared signal transmission with no blind spots Can receive instructions from other infrared remote controls and perform corresponding actions When paired with a microcontroller, can emit infrared commands to control electronic products such as air conditioners, fans, and other devices Benefits Wide, fullroom coverage: 360° transmission reduces blind spots and improves reliability in controlling devices from various positions Flexible integration: works with microcontrollers to generate and send IR commands Remote compatibility: can interact with existing remotes to reproduce or respond to commands Specifications and compatibility Infrared carrier frequency: 38 kHz Transmitting configuration: four infrared tubes located at the module corners Function: infrared transmission and reception with remote command execution capability Applications: suitable for controlling electronic products such as air conditioners, fans, and other IRcontrolled devices Use scenarios Scenario 1: Home automation hub. Place the module centrally in a room to reliably control multiple IR devices (air conditioner, fan, TV) via a connected microcontroller. Scenario 2: Remote consolidation. Use with a microcontroller to learn and reproduce commands from existing remotes, enabling unified control of several devices. Scenario 3: Prototyping and DIY projects. Build or test IR control systems that require widearea coverage and the ability to send commands to various appliances without blind spots.
