5. Using SensiNact, experimenters can find Internet of Things
devices which are deployed in the city, and understand the data
streams that they provide.
The SensiNact IDE allows the creation of applications using a
scripting tool (with Code Assist functionality). These applications
might set up alerts for when variables in the data streams reach
certain levels, or can aggregate data from many devices,
creating virtual devices which provide coarse data that might be
more useful to an experiment.
