360 degree infrared coverage The infrared transmitting and receiving module is arranged with four corners to achieve 360degree IR signal transmission with no blind spots. 38 kHz carrier infrared signaling Supports standard 38 kHz carrier infrared signal transmission for reliable remote control communication. Four transmitting elements in the receiving module The receiving module contains four infrared transmitting tubes, enabling strong, broad reach and redundancy. MCU friendly control and device compatibility When used with a microcontroller, it can emit infrared commands to control electronic products such as air conditioners, fans, and other IR controlled devices. Bidirectional infrared capability In addition to sending commands, it can receive instructions from other infrared remote controls and trigger corresponding actions in your project. Key benefits and why you need it Eliminates remote control dead zones with full room coverage. Enables integration with microcontroller projects. Supports control of common household appliances via infrared signals. Flexible use for both sending commands and learning/receiving from existing remotes. 23 practical use scenarios Scenario 1: Build a custom universal remote by pairing with a microcontroller to control multiple devices (air conditioner, fans, lights) from a single interface. Scenario 2: Create a home automation hub that continuously transmits IR commands to devices in the room, enabling scripted routines and automation. Scenario 3: Use the module to receive IR signals from existing remotes and translate them into actions within your microcontroller project (learning remotes and reusing signals). Performance and compatibility notes Key features include 360degree coverage, 38 kHz signaling, and the ability to both emit and receive IR commands through MCU interaction. Designed to work with standard IR remote protocols via a microcontroller, facilitating integration into embedded projects.
