Infrared LED Diode Transmitter 5mm – 940nm IR Emitter – Clear Lens

This 5mm Infrared LED Diode Transmitter operates at a 940nm wavelength, making it perfect for IR remote control applications, IR communication, and object detection systems. Designed with a clear round lens and a narrow 30° viewing angle, it emits invisible IR light not visible to the naked eye but easily detected by IR receivers or your phone camera.

It works just like a regular LED – apply voltage to the anode (longer lead) and connect the cathode (shorter lead) to ground. Add a series resistor to limit current, and you’re ready to go.

This LED is ideal for:

• Building custom IR remotes

• Creating IR-based obstacle detectors or beam sensors

• Use with IR receiver modules for Arduino or other microcontrollers

Note: Infrared light is not visible to the human eye. To verify operation, view the LED through a smartphone camera.
