A continuously-arranged sensor system is provided that can eliminate a shift in timing between a determination signal of each sensor unit and sensor information relating to the determination signal. The continuously-arranged sensor system includes a network unit and a plurality of sensor units, which are connected by a serial transmission line and a parallel transmission line. In accordance with a command sent from the network unit, each sensor unit transmits the determination signal and the sensor information, provided at the same time as the determination signal, to the network unit via the serial transmission line. Therefore, the network unit can obtain the determination signal and the sensor information exhibited at the same time.
