This project provides a service to allow people to monitor study rooms in real time. The users connecting to a web page are able to understand how many seats are free examining a map showed by the client. Such a map represents the geometry of the room and it reflects the real position both of the seats and of the table.
An high-level overview of this software is given by the picture below 
##Hardware The hardware chosen is a Spider Fez 2.0 (Microsoft .NET Gadgeteer platform), its task is to take a photo every n seconds and to send it to a serverTCP. The module communicates both with the web service and with the serverTCP.
##Web Service Web Service is a SOAP server based developed through WCF framework. It handles the authentication of the Gadgeteer and instances a new serverTCP every time that a photo have to be received. In fact each photo transfer takes place in a new tcp connection like the ftp protocol.
##Server TCP ServerTCP is a module that receives the photo, process it and update the database.
##Web Client Web client is the front end module. It uses a web socket that allow it to get the updated data in real time and refresh the graphics interface without any interaction by the user.
