  "description_en": "This parking-sensor investigation reconstructs the signal sent from a kit's controller to its display. Oscilloscope observations and tests with different sensor states identify fields in roughly 48-bit frames for sensor address, connection and proximity. A PlatformIO example for ATmega328P reads and reports the parsed frames.",
