How does it work?

The transmitter unit is placed on the river bank (at a point where water level reaches during flood) and the receiver unit is placed in a house of the nearest village. The house owner (known as caretaker) will take care of the unit and disseminate information received from the instrument to the downstream communities through mobile phone/SMS.

Process

  • As the power supply is connected to the units (transmitter and receiver), the transmitter establishes its network and starts communicating with the receiver at one-minute interval indicated by a blue LED light in the receiver unit.
  • As the water level rises up to the first sensor segment, the transmitter transmits this signal to the receiver and the receiver interprets it as level one indicated by yellow LED light.
  • If the water level rises up to the second sensor segment, the transmitter transmits second level signal to the receiver and the receiver interprets it as level two indicated by orange LED light and beep siren as pre alarm.
  • If the water level rises up to the third sensor segment, the transmitter transmits third level signal to the receiver and the receiver interprets it as level three indicated by red LED light and continuous ringing siren as final alarm.
