Patent Images
1. A sensor system comprising:
- plural sensor modules, having a unique identification data;
a connecting unit which has plural ports, having a unique address allocated thereto, and which connects the sensor modules to each of the ports;
a voltage generating unit which generates a different voltage for each of the addresses and supplies the voltage to each of the plural sensor modules; and
a control unit which communicates with the sensor modules via the connecting unit;
wherein the sensor moduledetermines the address of the port based on the voltage from the voltage generating unit, and transmits a physical quantity that is detected and the unique identification data to the control unit.

Abstract
A sensor system includes: plural sensor modules, each having a unique ID; a connecting unit which has plural ports, each having the sensor module connected thereto and having a unique address allocated thereto; a voltage generating unit which generates a different voltage for each of the addresses and supplies the voltage to each of the plural sensor modules; and a control unit which communicates with the sensor modules via the connecting unit. The sensor module determines the address of the port based on the voltage from the voltage generating unit, and transmits a predetermined physical quantity that is detected and the unique ID to the control unit.
