The TSOP1738 is a infrared receiver tuned to react only to IR of frequency 38 kHz. This IR sensor module consists of a PIN diode and a pre amplifier which are embedded into a single package. The output of TSOP is active low and it gives +5V in off state. When IR waves, from a source, with a centre frequency of 38 kHz incident on it, its output goes low. It is perfect for making obstacle sensors and to accept signals from most IR remotes.

TSOP Sensor Specifications:

  • Photo detector and preamplifier in one package
  • Internal filter for PCM frequency
  • Improved shielding against electrical field  disturbance
  • TTL and CMOS compatibility
  • Output active low
  • Low power consumption
  • High immunity against ambient light
  • Continuous data transmission possible (up to 2400 bps)
  • Suitable burst length ≥10 cycles/burst
