The DFRobot Gravity Digital IR Transmitter Module is a small infrared LED board that sends IR signals, meant to be paired with a matching IR receiver module for short-range line-of-sight communication. It uses the Gravity 3-pin connector, so it plugs into DFRobot I/O expansion shields and most microcontrollers with a simple digital pin. It is a building block for remote-control emulation, simple robot-to-robot links and light-trigger projects, not a standalone remote. Compared with bare IR LEDs, it saves wiring and driver circuitry, but it is a transmitter only and needs the receiver and your own code to be useful.

The Gravity Digital IR Transmitter Module sends infrared signals for wireless IR communication. It is designed to be paired with an IR receiver module.
The module uses an infrared LED and supporting circuitry. A signal sent to the LED is converted into a beam of invisible infrared light, which the receiving device detects and converts back into an electrical signal.
Like all IR technology, it needs a clear line of sight between the transmitter and the receiver. It cannot be used around corners or through walls or ceilings.
