加速度傳感器中有一種是三軸加速度傳感器，同樣的它是基于加速度的基本原理去實現(xiàn)工作的，加速度是個空間矢量，一方面，要準確了解物體的運動狀態(tài)，必須測得其三個坐標軸上的分量；另一方面，在預(yù)先不知道物體運動方向的場合下，只有應(yīng)用三軸加速度傳感器來檢測加速度信號。由于三軸加速度傳感器也是基于重力原理的，因此用三軸加速度傳感器可以實現(xiàn)雙軸正負90度或雙軸0-360度的傾角，通過校正后期精度要高于雙軸加速度傳感器大于測量角度為60度的情況。三軸加速度傳感器的好處就是在預(yù)先不知道物體運動方向的場合下，只有應(yīng)用三維加速度傳感器來檢測加速度信號。三維加速度傳感器具有體積小和重量輕特點，可以測量空間加速度，能夠全面準確反映物體的運動性質(zhì)。
