TSOP1838 Plastic 38kHz IR Distance Sensor Receiver

TSOP1838 IR Receiver Sensor

The TSOP1838 IR receiver is a precision infrared sensor module tuned specifically to 38kHz frequency, making it ideal for receiving signals from standard IR remote controls such as TV, AC, set-top box, and home theatre remotes.

This TSOP1838 IR distance sensor receiver integrates a PIN photodiode and a preamplifier IC within a compact plastic package, ensuring superior sensitivity and noise immunity. Compared to conventional IR receivers, it provides enhanced protection against ambient light interference, making it highly reliable for indoor and semi-outdoor environments.

The TSOP1838 is widely used in distance sensing, obstacle avoidance robots, wireless control systems, and home automation projects. With extensive library support available for Arduino, Raspberry Pi, and other microcontrollers, it allows quick decoding of remote control signals and seamless integration into embedded systems.
