Summary:To provide a sensor module and a measurement unit having excellent detection accuracy.SOLUTION: A sensor module has: a plurality of inertial measurement units that each have an angular velocity sensor device, an acceleration sensor device, and a signal processing circuit processing output signals from the angular velocity sensor device and the acceleration sensor device; and an oscillation circuit that transmits a synchronous clock for synchronizing the plurality of inertial measurement units with each other. One of the plurality of inertial measurement units has the oscillation circuit.SELECTED DRAWING: Figure 3 【課題】優れた検出精度を有するセンサーモジュールおよび計測ユニットを提供すること。【解決手段】センサーモジュールは、角速度センサーデバイスと、加速度センサーデバイスと、前記角速度センサーデバイスおよび前記加速度センサーデバイスからの出力信号を処理する信号処理回路と、を有する複数の慣性計測ユニットと、前記複数の慣性計測ユニットを同期する同期クロックを発信する発振回路と、を有する。また、前記発振回路は、前記複数の慣性計測ユニットの１つが有する。【選択図】図３
