Description

Description:

These infrared-emitting LEDs operate at 940nm and used for creating IR remote control or IR obstacle and intrusion sensors. 

KEY FEATURES OF IR EMITTER MODULE:

  • 940nm nominal wavelength
  • 3.3 and 5V compatible

Infrared is the light spectrum up around 940 nm that is commonly used for IR remotes and is outside the visible spectrum for the human eye.

These devices are very useful for adding IR capability to a project including everything from making a custom IR remote for your TV to creating a custom serial IR communication link for a robot project or to make an intrusion detector if the IR signal is blocked.  If you need a receiver for use with the transmitter, you may also want to pick up our IR phototransistor or IR receiver module.
