- 38 kHz carrier infrared signal transmission: supports standard IR remote communications with compatible devices. - Four corner emitters for 360° coverage: the transmitter array is arranged at the four corners to minimize blind spots and improve reach. - Easy control with a microcontroller: when paired with a microcontroller, it can emit infrared commands to control electronic devices such as air conditioners, fans, and other equipment. - IR reception for remote-based actions: it can also receive commands from other infrared remotes and trigger corresponding actions, enabling automation and remote replacement. - Practical applications: 1) Build a DIY universal remote hub to control multiple devices (AC, fans, etc.) via custom IR commands. 2) Create a room-wide IR repeater to operate devices from any position without pointing directly at the remote. 3) Capture and map existing remote commands to automated actions in a microcontroller-based project. - Reliable performance: designed for straightforward integration with standard IR control workflows and compatible hardware setups.
