PROJECT DESCRIPTION

The proposed system detects the possibility of occurrence of flash flood across the railway track or roadways by sensing the rising water level in rivers at a considerable distance away from the tracks or roads to alert the concerned authorities by SMS.

The proposed system uses a microcontroller of the 8051 family and a rectified-power supply. In this system, a GSM modem is interfaced to the microcontroller through a level shifter for communication. The flash food sensing circuit is interfaced to the microcontroller for sensing the water level.

Whenever  any  user  presses a button, used in place of rising water level to create a fault at a considerable distance from the respective track or road, then the information is sent to the microcontroller through a transistor logic.The microcontroller compares this information with the predefined data; if the information matches, then it sends the corresponding information over SMS to the respective authorities through a GSM modem. The microcontroller stores the mobile number. Thus, many lives and properties can be saved by this warning system.

The future scope of this project can be augmented by adding a very special feature of changing the stored phone number according to the user requirement. This can be achieved by interfacing an EEPROM along with a keypad to the microcontroller for storing the desired contact number.
