KY-022 Infrared Receiver

[nojvspine]

Device name: Infrared Receiver
Protocol: GPIO
URL of example product: https://arduinomodules.info/ky-022-infrared-receiver-module/
Further information e.g. data sheet:

With gpiod we use this receiver in pair with infrared LED so that it blinks and receiver gets the signal.
