KY-005 Infrared Emission/Transmitter Module (Arduino)

Infrared (IR) Transmitter perfect for Arduino. Infrared emission control, also known as infrared emitting diodes It can be directly converted into electrical energ. Light (black light), and can radiate out of the light emitting device is mainly used in various photoelectric switches and remote control transmitter circuit. Infrared emission control structure, principles and common light-emitting diodes are similar, but different semiconductor materials used. Typically gallium arsenide is used for  Infrared emitting diodes, (GaAs), gallium aluminum arsenic (GaAlAs) and other materials.
