How Does the KY-022 Infrared Receiver Work?

The KY-022 38kHz IR Receiver receives infrared light emitted by a compatible remote-control transmitter.

Many consumer infrared remotes encode their commands using short bursts of infrared light modulated around a 38kHz carrier frequency.

The KY-022 receiver detects these bursts, filters the carrier, and provides a demodulated digital signal at its output pin.

A microcontroller can read this signal and decode supported infrared remote-control protocols using appropriate software.

Important: The KY-022 does not automatically identify button commands. The connected microcontroller and software library must decode the received pulse sequence.

KY-022 Module Pinout

• S (Signal): Demodulated digital IR output
• + (VCC): Positive power supply, typically 3.3V or 5V
• - (GND): Ground connection

The module can be connected to an appropriate digital GPIO input on a compatible microcontroller.

Note: The order of the connection pins may differ between manufacturers. Always check the actual PCB labels before connecting power.

Arduino Compatibility

The KY-022 is compatible with Arduino UNO, Arduino Nano, Arduino Mega, and other suitable development boards.

A typical Arduino UNO connection is:

• KY-022 S: Arduino digital pin D2
• KY-022 +: Arduino 5V
• KY-022 -: Arduino GND

Arduino's IRremote library can be used to receive and decode commands from supported infrared remote controls.

Depending on the remote-control protocol, Arduino can respond to received commands by controlling LEDs, relays, motors, displays, or other suitable electronic components.

ESP32 and Raspberry Pi Compatibility

The KY-022 can also be integrated with ESP32 and Raspberry Pi boards.

For these 3.3V GPIO platforms, power the receiver module from a suitable 3.3V supply to ensure that its digital output remains compatible with the controller.

Use an appropriate IR receiver software library or infrared input driver to process the received signals.

KY-022 vs KY-005 Infrared Module

The KY-022 and KY-005 are complementary infrared communication modules.

• KY-022 IR Receiver: Detects and demodulates compatible infrared remote-control signals.
• KY-005 IR Transmitter: Emits infrared light signals generated by an external controller.

By combining both modules, developers can build simple one-way infrared communication and remote-control experiments.

KY-022 vs TSOP1738

Both the KY-022 and TSOP1738 are associated with 38kHz infrared signal reception.

The KY-022 is commonly provided as a ready-to-connect breakout board with a three-pin header, while TSOP1738 refers to a specific infrared receiver component that may be sold individually or mounted on another board.

Check the actual receiver IC and PCB configuration when selecting replacement modules.

Why Choose the KY-022?

Simple Digital Interface: Easy integration with suitable microcontroller GPIO inputs.

38kHz IR Reception: Compatible with many infrared remote-control transmission systems using an appropriate carrier frequency.

Compact Design: Fits conveniently into robotics and embedded electronic projects.

Low Power Consumption: Suitable for many low-power monitoring and control applications.

Educational Value: Useful for learning infrared communication, digital signal decoding, and electronic remote control.

Important Usage Notes

• The KY-022 is an infrared receiver, not an infrared transmitter.
• It is designed for modulated IR signals, typically around 38kHz.
• It does not directly measure object distance or detect obstacles.
• Actual reception range depends on transmitter strength, alignment, lighting, and interference.
• Not every IR remote uses the same carrier frequency or protocol.
• Verify the module pinout before applying power.
• Use a voltage compatible with the controller's GPIO input.
• Do not connect the module directly to AC mains or high-voltage circuits.
• Compatible software is required to decode remote-control button commands.
• The module is not intended for high-speed optical data networking.
