3W High-Power 940nm Infrared Transmitter Module

The 3W High-Power 940nm Infrared Transmitter Module is engineered for long-range IR communication, smart home automation, and custom remote control applications. Unlike standard low-power IR LEDs that offer limited range, this module features a high-power 3W IR emitting diode driven by an onboard transistor switching circuit. This design allows you to transmit strong, high-intensity infrared signals over extended distances without drawing excessive current directly from your microcontroller's GPIO pins, solving the common range limitation in DIY remote control projects.

This module is highly compatible with popular microcontrollers like Arduino, ESP32, ESP8266, and Raspberry Pi. It is ideal for building custom smart remote-controlled furniture, universal IR blasters, home automation hubs, and optical communication systems. By applying a modulated 38kHz carrier signal to the input pin, you can easily emulate standard remote controls for TVs, air conditioners, and other consumer electronics.
