實驗目的是研究出加速度感測器的詳細資料，用來作為實作的基礎。實作的目的是探討是否可以使用加速度感測器所產生的資料，加以計算並估計出目前所在的位置。 At present the MEMS gradually entered the application stage. The MEMS wafer is constructed with micro-structure and fabrication process of CMOS. By the wafer integrated, there have a chip with MEMS and micro-controller to be used in many kinds of aspect.
The present paper mainly studies whether may use the accelerometer which is part of MEMS, with the operation of the embedded system, and wireless transmission. We can achieve the goal of remote controller. In order to test the varying degree the acceleration, therefore chooses the development board which Freescale Inc. produces, makes experimental environment which implementation for the present paper needs.
The systematic structure uses two developments boards. One is test side, and another is receiving side. The test side is used the accelerometer and transmits by wireless that is used IEEE 802.15.4 to the receiving side. Then the receiving side use wire to transmit to PC.
The goal of experimental is studies the accelerometer which is the detailed material, uses for to take implementation foundation. The goal of implementation is discusses whether may use the data which the accelerometer produces. Then we use the data to calculate and to estimate the position of present.
