This is the IR receiver used in the Pololu IR Beacon. This sensor family features a wide operating voltage range and allows for relatively high data rates; this particular unit is tuned for a 56 kHz carrier frequency.

This IR demodulator from Vishay is a great general-purpose receiver for IR-based remote-control projects. It is optimized for data rates up to 4000 bits/s and bursts as short as six cycles, and the detector’s epoxy package serves as an infrared filter that helps eliminate noise from visible light sources. The operating voltage range is broad enough for 5 V and 3.3 V logic, and unlike some receiver modules, the TSOP34156 allows for continuous reception. The module’s output signal can be directly connected to a microcontroller; no additional external components are required.


  • Operating Voltage: 2.7 – 5.5 V
  • Carrier Frequency: 56 kHz
  • Max data rate: 4000 bps
  • Package: Through-hole with 0.1" lead spacing

See the resources tab for the TSOP341 datasheet.
