Wireless Sensor Network
A wireless sensor network (WSN) consists of spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, pressure, etc. and to cooperatively pass their data through the network to a main location.
The more modern networks are bi-directional, also enabling control of sensor activity. The development of wireless sensor networks was motivated by military applications such as
battlefield surveillance
They are now used in many industrial and consumer applications, such as industrial process monitoring and control, machine health monitoring, environment and habitat monitoring, healthcare applications, home automation, traffic control and so on.
Wireless sensor networks consists of a large number of small computers, sensor nodes,
like the one shown below that can sense its environment, compute, store information and communicate wirelessly. In general, it is not known beforehand where a node is going
to end up so the nodes set up an ad hoc network among themselves when they are deployed.
Wireless Sensor Node
Advantages of Wireless Sensors
- Much cheaper to deploy than wired sensors
- Sensor nodes can be added or removed easily
- Node location can be changed without rewiring
- Can be configured into different network topologies. Star, Mesh, etc
Data Visualization
At the base station, the incoming live streaming data can be displayed on a computer, stored in a database, and plotted on a web page for near-real-time viewing and analysis.
