A/D converter in turbidity sensor SEN0554
Jeffrey.White 2026-04-22 07:47:17 26 Views1 Replies There are 3 main pieces of the SEN0554: the emitter, detector, and small circuit board. In which piece is the A/D converter located? What is meant by “dirty data”?

Hi there!
The A/D converter is integrated on the sensor's circuit board; the emitter and detector only handle optical signal transmission/reception and do not perform analog-to-digital conversion.
Here, "dirty data" is not invalid data. It refers to the 8-bit normalized data (0~255) linearly mapped from the 12-bit raw AD data (0~4095), designed to simplify UART transmission and processing.
