A pre-embedded sensor for drop test comprises a shell, and a three-axis linear accelerometer, a three-axis angular accelerometer, a digital-to-analog conversion unit, a data storage unit and a wireless communication unit which are installed inside the shell. The three-axis linear accelerometer measures the linear acceleration in all directions of a 3D space in real time during drop test. The three-axis angular accelerometer measures the angular acceleration in all directions of the 3D space in real time during drop test. The digital-to-analog conversion unit converts data of the three-axis linear acceleration and the three-axis angular acceleration into digital signals, which are stored in the data storage unit and transmitted out through the wireless communication unit. 种用于跌落测试的预埋传感器，包括外壳、安装在所述外壳中的三轴线加速度计、三轴角加速度计、数模转换单元、数据存储单元和无线通讯单元，所述三轴线加速度计实时测量跌落测试时在三维空间各个方向上的线加速度，所述三轴角加速度计实时测量跌落测试时在三维空间各个方向上的角加速度，所述数模转换单元将所述三轴线加速度和所述三轴角加速度的数据转变为数字信号，并将这些数字信号保存到所述数据存储单元并通过无线通讯单元传出。
