Wireless Sensor Networks for Landslide Warning

In this paper, we are going to study about Landslide warning system, as the occurrence of landslides is a big loss for human life as well as property. We cannot stop the natural causes but we can be alert before they occur. So to alert people from landslides, we use this idea. In this design we have used five sensors of a Strain gauge is used to measure the strain on an object when force is applied to the board, the resistance of the gauge changes in accordance with the strain produced in the board. Soil moisture sensor generally used to detect the moisture content of the soil and compare the soil humidity with set threshold value. The tilt sensor is a component that detects the tilting of an object. Rain fall sensor is a type of water sensor might just be a good equalizer. Vibration sensor is used originally as vibration switch because of it is sensitive to environment vibration, and generally used to detect the ambient vibration strength. All sensors output is then given to Microcontroller ARM LPC2148 after desired processing the result are send to LCD display, GSM module and Buzzer for further communication, alert as well as analysis. The message from transmitter is send through transmitter GSM device and received by receiver side GSM, the information is given through SMS by GSM connected at receiver end. We have LCD receiver to observe the readings directly at receiver station without using SMS. Used APR9600 voice module which gives voice message alerting nearby places in danger. Thus this paper is very important as we use it in our real time purpose for saving lives and property. This design combines of GSM wireless communication technology and Wireless Sensor Network.
