TSOP1838 is an infrared receiver tuned to receive Infrared Light of frequency at 38kHz. This can be very helpful to read signals from most Infrared remotes like the one used on your TV, AC etc. The receiver has ambient light protection and perfect to use as an obstacle avoidance sensor when compared to normal IR receivers LED's. Great receiver for making wireless projects, robots, home automation systems, etc. This module is smaller than our TSOP1838 module. You can use both the modules for the same application, but the pinouts are different.
The receiver has three pins - +5V, Ground and Output.

  • Receives and amplifies the infrared signal without any external component
  • TTL and CMOS compatible
  • 38 kHz integrated oscillator
  • Immunity to ambient light
  • Low when active and 5V when Idle - Output Active Low
  • Improved shielding against electric field disturbance
  • Smaller than TSOP1738
