Generic 38kHz IR Transmitter Sensor Module - PCB Module
This 38kHz IR transmitter module generates a modulated infrared signal for remote control and optical switching applications, compatible with 3.3V/5V logic systems like Arduino, ESP32, and Raspberry Pi.
Features
- Generates a 38kHz modulated infrared carrier signal for reliable transmission.
- Low forward voltage operation (1.1V–1.5V) with a typical 20mA drive current.
- Compact PCB module format for easy integration into DIY electronics and prototyping.
- Designed for compatibility with common microcontroller platforms (Arduino, ESP32, Raspberry Pi).
- Utilizes a gallium arsenide (GaAs) based infrared LED for efficient near-IR emission.

This infrared transmitter module is built around a gallium arsenide (GaAs) or aluminum gallium arsenide (GaAlAs) infrared light-emitting diode (IR LED) that converts electrical energy directly into near-infrared light. The integrated circuitry modulates the output at a standard 38kHz frequency, which is essential for avoiding interference from ambient light and is the de facto carrier frequency for most consumer remote control protocols.
The module is supplied as a ready-to-use PCB with clearly labeled pins for power, ground, and signal input, simplifying integration into sensor arrays, remote control systems, and optical isolation circuits. Its construction ensures stable operation within specified electrical parameters.
