VS1838B Infrared Receiver Sensor

The VS1838B Infrared Receiver Sensor is a 38kHz IR receiver module designed to receive and decode infrared signals from standard remote controls. It integrates a PIN photodiode, preamplifier, automatic gain control (AGC), band-pass filter, and demodulator into a single package, making it ideal for Arduino, ESP32, Raspberry Pi, home automation, robotics, and remote-controlled electronics projects.
