Flash Flood Intimation Over GSM

The document describes a system to detect rising water levels in a river near a railway track and send an alert SMS to the station master's phone via GSM to stop trains and prevent accidents. The system uses an ultrasonic sensor connected to a microcontroller that monitors the water level and sends an SMS through a GSM modem if the sensor detects a flood. An LCD display shows the system status.

FLASH FLOOD INTIMATION OVER GSM

ABSTRACT:

The main objective of the project is to detect rising water level in a river
before the railway track at a reasonable distance from the rail track and intimate
that to the nearest station master through GSM, to detain train movement. A
programmable Microcontroller of Atmega family is interfaced with a water
level sensor. Sensor will send an interrupt to the microcontroller indicating that
it has crossed the danger point. So whenever there is an occurrence of such
flood the sensor sends a logic signal to the microcontroller that is programmed
in such a way that it will send an alert stored SMS through RS232 protocol to
the SIM mounted GSM modem to the station master’s mobile number to detain
train movement and to avoid accidents. An LCD display is also made to indicate
the status. The power supply consists of a step down transformer 230/12V,
which steps down the voltage to 12V AC. This is converted to DC using a
Bridge rectifier and it is then regulated to +5V using a voltage regulator
7805/7812 which is required for the operation of the microcontroller, Wi-Fi
modem and other components.
