The natural disasters like earthquake, tsunami and landslide as the occurrence of these disasters is a big loss for human life and property. Natural causes cannot be stopped but using this technique canalert people before it occurs. In this design, five sensors are used, those are angle or tilt sensor which gives the readings of slope angle if there is any movement due to the landslide and it is also used for tsunami alerting purpose, rain gauge sensor is used to collect the depth of water at the mountains, soil drift sensor is used for detection of landslide, earthquake sensors are used for earthquake detection purpose and temperature sensor is used for collecting the temperature. If any disaster occurs, sensor will sense the signal and output of sensor will given to the PIC microcontroller for further process. These all nodes of sensors are connected to the PIC controller for collection of data and obtained information is transmitted to the receiver section using RF module. Alerting message display'son LCD and message is sent in order to alert the people. Thus this project is very important as this is used for real time purpose for saving lives and property also this design combines the GSM wireless communication technology.
