KY‑022 TL1838 3‑Pin IR Receiver Module 38kHz Infrared Sensor for Arduino and Raspberry Pi DIY Kit

Universal 3pin infrared receiver module compatible with KY022 TL1838 VS1838B HX1838. Small, breadboardfriendly sensor that reads standard remote control signals and provides a clean, demodulated digital output for microcontroller projects. Key benefits Easy to integrate: Standard 3pin header (VCC, GND, OUT) plugs into breadboards and perfboards for fast prototyping. Wide compatibility: Works with common microcontroller platforms such as Arduino and Raspberry Pi and with IR libraries for quick development. Reliable signal decoding: Designed for the 38 kHz carrier frequency used by most consumer remotes, providing a demodulated digital output that simplifies software decoding. Low power and compact: Small PCB module consumes little power and fits into tight project enclosures. What it does and why you need it Receives infrared remote signals and converts them to a standard digital output that microcontrollers can read directly. This removes the need for raw analog processing and speeds up development. Enables remote control input, wireless triggering, and IR communication in DIY electronics, learning kits, and robotics projects. Saves time during prototyping by providing a plugandplay receiver that is already tuned for typical remote control frequencies. Key attributes Compatibility: Compatible with KY022, TL1838, VS1838B, HX1838 style IR receiver modules and standard IR remote protocols. Operating voltage: Works with common logic voltages (3.3 V to 5 V). Carrier frequency: Optimized for 38 kHz infrared signals used by most remote controls. Output: Demodulated digital output suitable for direct connection to microcontroller digital input pins. Size and form factor: Compact PCB module with standard 3pin header for easy mounting on breadboards, shields, and custom PCBs. Construction: Typical PCB and plastic IR receiver housing for durable everyday use. Quick wiring and use Pins: VCC to 3.3 V or 5 V, GND to ground, OUT to a digital input pin. Software: Use a standard IR remote library or basic pulse measurement routines to decode button presses. No extra analog circuitry required thanks to the demodulated output. Practical application examples Remotecontrolled projects: Add infrared remote control to a DIY media center, toy vehicle, or robot for wireless command input. Home automation prototyping: Receive commands from standard TV remotes to toggle relays, control lights, or trigger scenes during development. Learning and experimentation: Use in starter kits and electronics classes to teach infrared communication and signal decoding with minimal setup.
