Fea tures
  • Its directly give the digital forms of data.
  • TSOP 1738 used as photo detector.
  • High Reliable.
  • Low cost
  • Photo Diode (IR sensor) tuned to 38 KHz, perfect for receiving commands from a TV remote control. Runs at 3V to 5V so it's great for any microcontroller.

  • To use, connect pin 3 (all the way to the right) to 5V power, pin 2 (middle) to ground and listen on pin 1. It doesn't do any decoding of the signal, just passes the 'raw data' along.
