Once you have raw counts (e.g., ADC reading = 2048), apply the inverse transfer function. Volta sensors are rarely linear. The standard decoding equation is: Physical_Value = A * log10(Raw_Count - Offset) + B Where A and B are constants from the sensor’s unique calibration certificate.
For asynchronous protocols, the Volta sensor embeds a clock in the data. Use a transition detection algorithm: measure the shortest pulse width—that is your bit period. Volta Sensor Decoding
Use an oscilloscope to probe the sensor’s output pin. Set the time base to 100 µs/div. Look for repeating patterns. Is the signal analog (smooth sine) or digital (sharp square)? Once you have raw counts (e
Identify the start bit. Volta sensors typically use a 9-bit framing : 1 start (low), 8 data, 1 parity (odd/even), 1 stop (high). Write a simple Python script using pySerial to sample the pin via a logic analyzer. For asynchronous protocols, the Volta sensor embeds a
