This document discusses the Internet of Things (IoT). It begins with definitions and examples of IoT, describing how physical devices collect and transmit data via sensors to cloud services for analysis and to provide information to smart devices. It then discusses the components that make up an IoT system including sensors, connectivity between devices and the cloud, and consumers or smart devices. The document also compares IoT to machine-to-machine communication (M2M) and provides examples of IoT applications. It introduces the Torrentio platform for building IoT applications without programming and discusses upcoming developments in IoT technologies and potential next steps like starting a DIY project.
