VS1838B IR Receiver

The VS1838B is a high-sensitivity infrared receiver module widely used for remote control and wireless signal reception in Arduino, ESP32, and microcontroller-based projects. It integrates a photodiode, amplifier, and demodulator in a single 3-pin package, operating at the standard 38kHz carrier frequency for compatibility with most household and DIY IR remotes. Features include a wide 5V/3.3V operating range, low power consumption, strong ambient light immunity, and a built-in signal output pin (OUT) that connects directly to a digital input on Arduino UNO, Nano, ESP32, ESP8266, and Raspberry Pi. Ideal for building TV/AC remote decoders, IR-controlled robots, home automation systems, security systems, and general robotics/IoT projects. Includes 3-pin header (VCC, GND, OUT) for direct breadboard or jumper wire connection — no additional components required for basic operation.
