Gravity:DIGITAL IR Transmitter Module (DFR0095)
€3,75 (€4,65 inc tax)
DFRobot, DFR0095, 5212019508339

An infrared transmitter is simply a Light Emitting Diode which generates IR light (invisible IR light)--light with a wavelength of between 1 mm and 750 nanometers, and some associated circuitry. In an infrared remote control, for example, pushing a button sends an electric signal to the LED, which converts the signal into a beam of infrared light. The receiving device detects the light with a photo diode and converts it to an electrical signal which, via an integrated circuit, controls its actions.
