VS1838B HX1838 Universal Infrared IR Receiver Module 38kHz

📡 VS1838B / HX1838 38kHz Infrared Receiver Module (3-Pin)

This is the classic IR receiver module for remote-control projects: a VS1838B photodetector on a small breakout board that demodulates 38kHz infrared remote signals and hands you a clean digital pulse train. Pair it with any NEC-format TV/AC remote and an Arduino, and you have remote control in a few wires.

✨ Key Features

• 38kHz carrier demodulation — rejects sunlight and ambient light noise.
• 3-pin interface: VCC, GND, OUT — the output is already demodulated, so no extra circuitry.
• Works with the standard 38kHz remote protocol family (NEC and compatible formats).
• On-board decoupling and pull-up for a stable output signal.
• Compact module with 2.54mm header spacing, breadboard friendly.

📋 Specifications

• Receiver: VS1838B (HX1838 equivalent)
• Carrier frequency: 38kHz
• Wavelength: ~940nm infrared
• Supply: 2.7-5.5V DC (5V typical)
• Output: digital, active-low demodulated signal
• Pins: VCC / GND / OUT
• Reception: wide front-facing acceptance angle

🔧 Perfect for

• Arduino/ESP32 IR remote decoding projects and libraries like IRremote
• Media centres, robot cars, and home-automation remotes
• Learning about modulation and digital signal decoding
• Replacing a dead IR receiver in TVs, audio gear, or set-top boxes

Point the receiver at the remote, keep it out of direct sunlight, and decode with a library that matches your remote's protocol.
