Description

The Universal IR Infrared Receiver TL1838 / VS1838B is a high-sensitivity infrared receiver module designed to receive 38KHz modulated IR signals used in most remote control systems. It is commonly used in TV remote controls, Arduino projects, Raspberry Pi projects, home automation systems, and consumer electronics.

This module features a built-in metal (iron) shielding shell that improves noise immunity and ensures stable signal reception even in environments with electrical interference.

The receiver integrates a photodiode, amplifier, and demodulator circuit, making it easy to interface directly with microcontrollers and digital circuits.

Its compact design, reliable performance, and low power consumption make it ideal for electronics hobbyists, engineers, and product developers.
