The HW-489 module is built around a 5mm infrared-emitting diode (LED) that operates on the 940nm wavelength, which is invisible to the human eye but easily detected by IR receivers. Specification Operating Voltage Wavelength ~940nm (Infrared) Emission Angle Approximately 20 degrees Signal Type Maximum Distance ~1.3 meters (at 5V 38kHz) Dimensions 13.7mm x 27.8mm Pinout and Hardware Design
The HW-489 is a 38kHz infrared transmitter module (often part of sensor kits) used with microcontrollers to emit 940nm light for remote control functionality. It operates via three pins—Signal, VCC, and GND—and is commonly programmed using libraries like IRremote to send signals compatible with consumer electronics. For more details, visit Arduino Forum .
