The aim of the Reactivity sensor network is to provide enterprise and city-level networking of sensor and device control systems.

Microsoft XML web services would provide a robust yet flexible network of environmental sensors. Possible sensors are AC current, temperature, humidity, light, sound, carbon dioxide and monoxide, and motion. Users can acquire any sensor data by connecting to any one of the nodes in the network. The network can be configured and programmed using customized rules. Different actions can be scheduled to happen once certain environmental conditions are met in the targeted environment. Microsoft SQL Server would be used to store sensor position and configuration information as well as sensor data for future study and analysis. Mobile phone users would be able to access sensor data as well as control environment remotely through a .NET device application developed on .NET Compact Framework.
