The Internet of Things (abbreviation: IoT) refers to the connection of machines and objects (e. g. sensors or controllers) to the Internet. These things communicate independently via the Internet and thus accomplish a variety of tasks.
Possible applications range from general information exchange to automated ordering, alerts and emergency notifications.
Depending on the frequency of data transmission or the required bandwidth, these things can be connected to the Internet wired, via WiFi or a LPWAN.
