The sensor-id in the sample struct was a uint8_t, with all the known problems of unsigned integers. In the rest of the code cylinder ids are signed integers. To avoid confusion, make it a signed int. int8_t should be enough (max. 127 cylinders). To allow for degenerate cases, use an int16_t. 16k cylinders should be enough for everyone.
