本发明之课题系按可对测定对象造成影响之外部指针的变化，适当地设置用以测定测定对象之传感器的测定条件。 传感器系统包含有第1及第2传感器、判定部、测定条件记忆部、及控制部；该判定部用以于第1传感器之测定结果满足预先订定之条件时，输出检测信号；该测定条件记忆部用以存储第2传感器之测定条件；该控制部用以于接收检测信号时，除了根据测定条件之测定外，另外还运行第2传感器之测定，并依据该测定之测定结果，更新存储于测定条件记忆部之第2传感器的测定条件。

In order to appropriately set a condition for measurement of a sensor for measuring an object to be measured in accordance with a change of an external index that can affect the object to be measured, a sensor system includes first and second sensors, a determination unit for outputting a detection signal when a measurement result of the first sensor satisfies a predetermined condition, a measurement condition storage unit for storing a condition for measurement of the second sensor, and a control unit for performing measurement by the second sensor separately from measurement in accordance with the condition for measurement, when having received the detection signal, and for updating the condition for measurement of the second sensor stored in the measurement condition storage unit based on a result of the performed measurement.
