HX1838 VS1838 NEC IR Remote Control Sensor Module | Compoden
HX1838 VS1838 NEC Infrared IR Remote Control Sensor Module – 38kHz IR Receiver
The HX1838 (also labeled VS1838) is a compact infrared receiver module designed to demodulate and decode NEC protocol signals from standard IR remote controls. It is perfect for adding wireless control to Arduino, ESP32, Raspberry Pi, or other microcontroller projects. This module provides reliable reception at distances up to 10 meters with its 38kHz carrier frequency.

Compatibility
Compatible with any 3.3V or 5V microcontroller, including Arduino Uno, Nano, Mega, ESP8266, ESP32, and Raspberry Pi. Connect the OUT pin to a digital input and use the IRremote library for straightforward decoding. The wide voltage range makes it suitable for both 3.3V and 5V systems.
Wiring Notes
Connect VCC to 3.3V or 5V, GND to ground, and OUT to a digital pin (e.g., Arduino pin 2). No external pull-up resistor is required; the module includes built‑in filtering and demodulation circuitry. Keep the sensor’s face unobstructed for maximum range.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino Uno?
Yes, it works directly with the Arduino Uno. Wire VCC to 5V, GND to GND, and OUT to digital pin 2, then use the IRremote library to decode signals.
What is the maximum range of this IR sensor?
Under ideal conditions with a clear line of sight, the module reliably receives signals up to 10 meters. Obstacles and bright ambient light may reduce effective range.
Will it work with any IR remote?
It decodes the NEC protocol used by many consumer remotes. If your remote uses a different protocol (e.g., Sony SIRC), you can still capture raw timings with appropriate library support.
