Recently, Micro-Electro-Mechanical-Systems (MEMS) based accelerometers become a good candidate for replacing the geophone and inclinometer in landslide monitoring. By integrating different kinds of sensors to each node of a communication system, Wireless sensor network (WSN) is a good facility to measure and remote monitor the environment's parameters. Obviously, the cost of the WSN needs to be reduced in order to set-up the systems in many more wide, unstable slopes. However, for a low-cost solution, there is no Wireless Accelerometer Network (WAN) could provide all information of vibration, inclination, and displacement at once due to essence drawbacks of MEMS based sensors. Therefore, in this paper, we explored the use of low cost, three degrees of freedom (3-DoF) ADXL335 chip based MEMS accelerometers to measure and real-time monitor the inclination, the vibration, and the displacement of the soil slope. Both deterministic and stochastic errors are investigated to maximally reduce the incorrectness from sensors. Several signal processing algorithms are applied to provide the accurate information of the inclination and vibration. For the displacement estimation, a novel procedure is proposed to eliminate the accumulated error.
