Abstract
Abstract A drastic change in environmental conditions and geographical conditions causes big disasters. To save lives, monitoring of these changes is a big challenge. Along with monitoring, corresponding action to be taken within time limit is also important. To achieve this objective timely information about it is required. In this paper a Zigbee based system is proposed for disaster monitoring and management. Paper talks about wireless monitoring of water levels of group of dams and due to drastic change in water level in any river/lake, when to open the gate of which dam and upto which limit. It is decided with the help of sensory data collected from different nodes, placed over an area. The system comprises three parts, sensor nodes, local control room and centre control room. The monitoring is done with the help of data collected from sensor nodes(comprising water level sensor and rain sensor) and discharge sensors are used to control the opening of gates upto certain limit. All the decisions are taken through centre control room, by giving commands to different local control rooms after observing conditions of all areas. A hooter is also available with local control room node to indicate danger alert if water level crosses danger level.
