To provide a technique for an acceleration sensor that can be shared between navigation and a drive recorder.SOLUTION: A sensor system includes: an acceleration sensor; a detection unit that outputs an interruption signal when the acceleration sensor detects an acceleration value more than or equal to a predetermined threshold value; and a processor that, upon input of the interruption signal, switches a detection range of the acceleration value of the acceleration sensor to a second detection range wider than a first detection range.SELECTED DRAWING: Figure 3
【課題】ナビゲーションとドライブレコーダとの間で共用可能な加速度センサの技術を提供する。【解決手段】センサシステムは、加速度センサと、加速度センサが所定の閾値以上の加速度値を検出したときに割込み信号を出力する検出部と、割込み信号の入力を契機として、加速度センサの加速度値の検出範囲を第1検出範囲より広範囲な第2検出範囲に切換えるプロセッサと、を備えることを特徴とする。【選択図】図3
