Product Description

Universal IR Infrared Receiver Sensor Module 1838

= 38kHz Infrared Receiver for Remote Control Applications =

The Universal IR Infrared Receiver Sensor Module is a compact and highly sensitive component designed for receiving and demodulating 38kHz infrared signals from standard remote controls. This versatile module integrates a photodetector and preamplifier in a single package, making it an essential component for remote control receivers, automation projects, and Arduino-based systems.

Integrates photodetector and preamplifier in single package
Requires pull-up resistor (<20kΩ) for proper output operation
Input voltage range: 2.7V to 5.5V - do not exceed

= Key Features =

38kHz Carrier Frequency - Compatible with most consumer remote controls (NEC, RC5 codes)

Integrated Design - Photodetector and preamplifier in one package simplifies circuit design

High Immunity - Excellent resistance to ambient light and electromagnetic interference

Wide Operating Voltage - 2.7V to 5.5V for versatile applications

TTL/CMOS Compatible - Direct interface with microcontrollers and digital circuits

Low Power Consumption - Only ~1.5mA typical current draw

= Applications =

  • TV, DVD, and set-top box remote control systems
  • Home automation and smart lighting
  • Arduino and Raspberry Pi projects
  • Robotics remote control
  • Air conditioner and fan remote receivers
  • Industrial remote control equipment
  • Consumer electronics remote control
  • Wireless data transmission systems

= Pin Configuration =

PinFunctionDescription
1OUTSignal output (active low)
2GNDGround (0V)
3VCCPower supply (2.7-5.5V)
Pinout may vary between manufacturers - verify with datasheet
Common pinout: Left to right when facing flat side - OUT, GND, VCC

= How It Works =

  1. The photodetector receives infrared light signals from a remote control
  2. Internal amplifier boosts the weak signal
  3. Bandpass filter isolates the 38kHz carrier frequency
  4. Demodulator extracts the encoded data pulses
  5. Output pin produces a digital signal that can be decoded by a microcontroller
The sensor ignores ambient light and other interference signals
Output is normally HIGH and goes LOW when valid signal is received

= Wiring Guide =

Sensor PinArduino PinDescription
VCC (Pin 3)5VPower supply (2.7-5.5V)
GND (Pin 2)GNDGround
OUT (Pin 1)Digital PinSignal output
Add a 10kΩ pull-up resistor between VCC and OUT for stable operation
For clean operation, add a 10µF capacitor between VCC and GND close to the sensor
Do not connect output directly to VCC or GND - will cause malfunction

= Output Characteristics =

ConditionOutput StateExplanation
No IR SignalHIGHSensor idle state
Valid IR Signal ReceivedLOW (pulsing)Active low output responds to 38kHz signal
Output is opencollector requires pull-up resistor to function correctly
The output will pulse LOW in patterns that correspond to transmitted remote control codes

= Why Choose This IR Receiver? =

Universal compatibility with standard 38kHz infrared remote controls
Excellent ambient light rejection prevents false triggering
Built-in noise filtering provides reliable reception even in noisy environments
Simple 3-wire interface for easy integration
Cost-effective and readily available
Works with all common IR remote control formats (NEC, RC5)

√ Compatible with Arduino, ESP32, and all microcontroller platforms

√ Direct replacement for VS1838B, TL1838, HX1838 variants

√ No additional components required besides pull-up resistor

√ Wide receiving angle for flexible mounting

√ Long receiving range up to 25 meters

= Safety Precautions =

Do not exceed 5.5V supply voltage
Ensure correct polarity (VCC/GND)
Keep sensor window clean and unobstructed
Protect from direct sunlight or strong artificial light sources
Avoid electrostatic discharge (ESD) when handling
Sensor window should face the direction of the expected infrared signal source
For best performance, position sensor at receiver angle specified in datasheet
