Abstract: A component sensor detects a fluid component with improved accuracy. The component sensor includes tube (3) including tube side (4) that permits inflow of fluid (2), substrate (5) provided to tube (3), first protrusion (6) provided at one end of substrate (5), second protrusion (7) provided at another end of substrate (5), light emitter (9) that emits infrared light (8) toward first protrusion (6), and light receiver (10) that receives infrared light (8). Infrared light (8) entering substrate (5) through first protrusion (6) experiences total reflection inside substrate (5) and exits through second protrusion (7) to head for light receiver (10). Tube side (4) includes two through holes (13) that each extend between an interior and an exterior of tube (3). Substrate (5) is inserted into through holes (13) with a central part of substrate (5) being inside tube (3) and with the one end and the other end of substrate (5) that are respectively provided with first protrusion (6) and second protrusion (7) being outside tube (3).

Abstract: Provided are an analog-to-digital (AD) converter, a sensor system, and a test system capable of reducing the time for test processing. AD converter includes input part, AD conversion part, first output part, and second output part. The analog signal output from sensor is input to input part. AD conversion part digitally converts an analog signal to generate first digital data and second digital data. First output part outputs the first digital data to control circuit. Second output part outputs the second digital data to test controller before first output part outputs the first digital data. In the test mode, test controller determines whether or not sensor system including sensor is in an abnormal state on the basis of the second digital data.

Abstract: Provided are an analog-to-digital (AD) converter, a sensor processing circuit, and a sensor system capable of improving responsiveness of feedback control. AD converter includes input part, AD conversion part, first output part, and second output part. The analog signal output from sensor is input to input part. AD conversion part digitally converts an analog signal to generate first digital data and second digital data. First output part outputs the first digital data to control circuit. Second output part outputs the second digital data to sensor before first output part outputs the first digital data.
