The KY‑022 is an infrared receiver module designed to detect 38 kHz modulated IR signals, such as those from TV or stereo remote controls, IR transmitters like the KY‑005, or other IR communication sources. It provides a digital output that can be read by microcontrollers such as Arduino, Raspberry Pi, ESP32, ESP8266, and more for remote control and wireless input projects.
Key Features
Carrier Frequency: Approx. 38 kHz, compatible with standard IR remotes.
Operating Voltage: 2.7 V – 5.5 V DC – suitable for most development boards.
Operating Current: ~0.4 mA – 1.5 mA.
Reception Distance: Up to ~18 m (varies with transmitter power).
Reception Angle: Around ±45°.
Digital Output: Logic output that changes state when an IR signal is detected.
Interface: 3‑pin connection: VCC, GND, OUT for power and signal.
LED Indicator: Built‑in LED usually lights when IR is detected.
Overview:
The KY‑022 module integrates an IR receiver (often chip VS1838B) with minimal additional components to provide a ready‑to‑use IR sensor. It filters ambient light and outputs a clean digital signal when modulated IR light is received, making it ideal for remote control decoding, wireless trigger input and interactive projects.
Typical Uses:
IR remote control interfaces for LEDs, motors, relays and devices.
Wireless input detection for microcontroller projects.
Smart home controls based on IR remotes.
Educational electronics and hobby projects.
Tip: Libraries like IRremote make it easy to decode signals from many types of IR remotes and use them in your Arduino or other microcontroller code.
