The VS1838B IR Receiver Sensor is a compact and highly sensitive 38kHz infrared receiver used to receive signals from IR remotes. It’s ideal for building projects that involve remote control, such as TV remote automation, IR-controlled robots, or IoT home appliances.

Compatible with Arduino, ESP32, Raspberry Pi, and other development platforms, it outputs a clean digital signal when it detects a valid IR pulse train, making it easy to decode remote commands using libraries like IRremote.

Key Features:

Model: VS1838B

Operating Voltage: 3.3V – 5V

Carrier Frequency: 38kHz (standard for most TV remotes)

Output: Digital (active LOW)

Built-in demodulation circuit

Long-range reception: up to 8–10 meters

Low power consumption and high sensitivity

Ideal for Arduino, ESP32, NodeMCU, Raspberry Pi

Applications: IR remote control projects, IR-based automation, TV remote interfacing, IR learning devices
