In this chapter the final state of the system will be described. This chapter
will also discuss opportunities for further development, along with a short
discussion of how testing was used in the project.

System Summary
The finished system is a prototype, designed to be stable and functional to
a degree that makes it suitable for testing its functionality in near reality
environments. Structurally the system consists of four main components: A
sensor, a hub, the system server and the front-end web application. Two additional components have been added as a result of changes that happened in
sprint three, see chapter 10. The additional components are an app running
on a smart phone and a third party server. These were introduced in order
to facilitate a replacement sensor, but much of the original architecture was
maintained in order to make the system modifiable and thus compatible with
other sensors.
The sensor monitors the wearers heart rate, blood O2 saturation, and
activity. Data is sent from the sensor, via a mobile app and a third party
server, to the hub. The hub then passes the data to the system server, where
it is stored and analysed for abnormal values. The server maintains a list of
alarms that it generates when it receives abnormal values from a sensor. The
data on the server is accessible for healthcare professionals and users using
the system’s web application. While healthcare professionals have access to
