In order to overcome the disadvantages such as wired transmission and manual notification in conventional pre-warning systems for mountain landslide,this paper proposes a low-power and high-accuracy remote monitoring system for mountain landslide,which is designed with a three-axis acceleration sensor MPU6050.The system uses ZigBee wireless network to collect sensor data and utilizes Kalman filtering algorithm to reduce deviation in the result to improve higher accuracy.After being tested with physical prototype,the system runs stably and meets the design requirements well.
