In a nutshell, IoT works in the following way: 

  • Devices have hardware like sensors, for example, that collect data. 
  • The data collected by the sensors is then shared via the cloud and integrated with software. 
  • The software then analyzes and transmits the data to users via an app or website. 


Internet-of-Things devices are all around us; constantly transmitting data and “talking” with other IoT devices. We come across IoT devices almost everyday in the form of virtual assistants, “smart” electronics and in our wearable health trackers. Each Internet-of-Things device tracks information in real-time and relays it to us to help make our lives safer, healthier or more efficient.

Smart devices connect to an IoT platform, described by the experts at IoT For All as “the support software that connects everything in an IoT system.” There are hundreds of IoT platforms and some are made by such industry giants as Oracle and IBM.
