IR Transmitter

Description

Infrared LED. Can be used to make a remote control, or transmit information over IR.

Also called: IR emission, infrared transmitter, KY005.

Found in kits: 20 sensors, 37 sensors, 45 sensors.

Specification/Notes:

• Voltage: 3.3V to 5.0V
• Current: 20 - 30mA max typical
• LED: Power
• IR wavelength: 825-940nm
• Not modulated.
• Size: 20mm X 60mm
• Infrared light is outside of the normal light "color" detectable by the human eye.

There are a number of different sources for these modules. Not every module that looks similar to the ones here behaves exactly the same. Check the specific module that you have for differences in function, voltage levels, pinout, and inactive/active states. Some modules have been found to have incorrectly labeled pins and even poorly soldered components.

IR LED should be used with a current-limiting resistor (typically 100-330 ohm). If this LED is to be used as an IR remote control, it will need to be modulated with a 38kHz (typical) signal.

Module Pin-out:
