Generic Infrared IR Receiver Module for Arduino - 38kHz TSOP1838 Sensor
This TSOP1838-based infrared receiver module is designed for Arduino and other 3.3V/5V microcontroller platforms, decoding standard 38kHz modulated signals from common remote controls for automation and control projects.
Features
- TSOP1838 IR receiver tuned for 38kHz carrier frequency.
- Wide 2.7V to 5.5V operating voltage range for 3.3V/5V logic compatibility.
- High immunity to ambient light (up to 500 lux) and electromagnetic interference.
- 90-degree receiving angle with a line-of-sight range up to 18 meters.
- Compact PCB module with three-pin interface (VCC, GND, OUT) for easy integration.

This module integrates a TSOP1838 infrared receiving head, a dedicated IC for demodulation, and supporting components onto a compact PCB. It demodulates the 38kHz carrier frequency commonly used by consumer IR remote controls, outputting a clean digital signal for direct connection to a microcontroller’s digital input pin. The built-in AGC (Automatic Gain Control) circuit ensures stable operation under varying signal strengths and ambient light conditions up to 500 lux.
Designed for seamless integration with development boards like Arduino, ESP32, and Raspberry Pi, the module simplifies adding IR remote control functionality to DIY electronics, home automation systems, and robotics. Its three-pin interface (VCC, GND, DATA) follows a standard layout, requiring only a single digital pin on the host controller for full bidirectional communication when paired with a compatible IR transmitter.
