We describe a new visualization system for showing sensor network managers the state changes of sensor nodes in a LSWSN in a scalable way. This system called VSWSN intuitively visualizes the state of the whole network real-time, detecting anomalies from sensor data collected by a LSWSN, and notifying in advance some possibility of anomalies that might occur in the near future using Petri net. This VSWSN will be useful as a management tool for not only monitoring in such as present cloud computing centers and plant factories, but also prevention of disasters and environmental preservation..
