ALLNET 4duino IR Receiver / Infrared Receiver 38KHz Overview
This IR demodulator from Vishay is a general-purpose receiver for IR-based remote-control projects. It is intended as detector for data formats that are modulated at 38 kHz and have at least 10 cycles/burst popular IR codes that meet these requirements are NEC, Sharp, and r-step (our Mini IR Remote Control uses NEC encoding, so it works well with the TSOP38438). The module?s output signal can be directly connected to a microcontroller no additional external components are required. See the TSOP38438 datasheet (132k pdf) for more information.
For a similar IR detector that is tuned for a 56 kHz carrier frequency, see the Vishay TSOP34156.
