Seeed Studio Studio Grove Infrared Emitter v1.2 - 940nm, 10m Range, Grove Interface

The module operates from 3.3V to 5V DC, making it directly compatible with most development boards like Arduino (5V) and Raspberry Pi (3.3V) without requiring a level shifter. Ensure your Grove base shield or controller provides one of these voltage levels on the VCC pin.

You can use the emitter with an Arduino and a library like IRremote to emulate remote control signals. Connect the module's signal pin to a digital output on your Arduino, program it to transmit the specific IR code protocol (NEC, Sony, etc.) of your appliance, and aim the emitter at the device's IR receiver.

Under typical conditions with a clear line of sight and a compatible receiver (like the Grove Infrared Receiver), the emitter can reliably transmit signals up to 10 meters. Beyond this range, signal strength diminishes, and the receiver may not correctly decode the transmission. Performance can be affected by ambient IR light and obstacles.

Yes. The Grove connector breaks out to four standard pins: VCC (3.3V-5V), GND, and a digital signal pin. You can solder wires directly to these pads or use Jumper wires to connect it to any microcontroller's GPIO, provided you supply the correct operating voltage within the 3.3V to 5V range.
