IR Infrared Transmitter Module 38kHz Digital Sensor for Arduino, Remote Control & DIY Electronics

Description

The 38kHz IR Infrared Transmitter Module is an electronic building block used to transmit infrared signals at a frequency of 38kHz. It contains an infrared LED and a driver circuit mounted on a compact PCB, making it easy to connect directly to Arduino, ESP32, Raspberry Pi, and other microcontrollers. This module is commonly used in remote control systems, wireless IR communication, sensor projects, obstacle detection, and robotics. It works by generating a 38kHz infrared signal that can be detected by compatible IR receiver modules such as VS1838B, HX1838, and TSOP1738. Its compact size, low power consumption, and easy interface make it ideal for students, hobbyists, and engineers building
