Design of the Wireless Tilt Sensor Network Node

In this paper, a novel design method of the wireless tilt sensor network node is presented. Firstly, acceleration is measured by the MEMS-based biaxial acceleration sensor ADXL202, so, there are several advantages, such as low power consumption, simple external circuit and so on. Then, tilt could be calculated from acceleration. In the software development, calculating tilt signals and point-to-point wireless communication are realized, based on the famous wireless sensor network embedded operating system TinyOS. Experimental results have showed that the node could meet the performance requirements of the wireless tilt sensor network.
