Design of Zigbee Based Wireless Sensor Network for Early Flood Monitoring and Warning System

This paper proposes architecture for an early flood monitoring and warning system to alert public against flood disasters. The frequent occurrence of flood causes great harm to people's lives and properties. The proposed warning system is developed with the objectives to gather nvironmental information, and based on the collected data, alert the authorities and the population at risk autonomously. This project focuses on monitoring water level remotely using wireless sensor network (WSN). It also utilizes Zigbee network, Global System for Mobile communication (GSM) and Short Message Service (SMS).The system measures water level through wireless sensor nodes. The information is sent to the base station using Zigbee protocol. Data received from each node is stored in the database of the monitoring centre. In critical condition, early-warning SMS is forwarded to alert the victims using GSM technology. Microsoft Visual Basic 6.0 is used to implement the software. Based on GUI provided, administrative departments can take effective measures. The proposed architecture can be beneficial to the community and act as a precautionary action to save lives in the case of
flood disaster.
