Description
The KY-022 Infrared Receiver Module is a compact and reliable sensor designed to receive IR signals from standard remote controls, making it ideal for Arduino, Raspberry Pi, and microcontroller projects.
This module uses a 1838B IR receiver, tuned to a 38kHz frequency—standard for most TV remotes and IR transmitters. It outputs a digital LOW signal when it receives valid IR pulses, allowing you to decode and respond to remote control commands in your projects.
It’s perfect for building IR-controlled robots, media centre remotes, smart home automation, or DIY IR receiver circuits. With its simple 3-pin interface, it integrates easily with any development board.
