# Parking sensor kit: reconstructing its display protocol

> 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.

## Requirements & limits

- **Prerequisites:** The example targets an ATmega328P microcontroller and a compatible parking-sensor kit.
- **Prerequisites:** Check signal voltage before connecting a microcontroller; the documented unit exceeded 5 V.
- **Limits:** Controller electronics vary across similar kits, so the code may need changes.
- **License:** No licence file in the repository.
