Before you decode, you must respect the physics. A Volta sensor generates a signal through ionic or electron displacement.
This is where the continuous voltage becomes discrete numbers.
Implement Ratiometric Out-of-Range Detection . Design your hardware and transfer functions so that valid sensor states only span from 10% to 90% of the supply voltage (e.g., 0.5V to 4.5V). If the decoder registers a voltage below 0.3V or above 4.7V, it flags an immediate sensor hardware fault code (Short-to-Ground or Short-to-Battery) and enters a safe fallback state.
