Internet of things (IOT) is a network of physical objects. IOT is a sensor network of billions of smart devices that connect people, systems and other applications to collect and share data.
The internet of things is also a natural extension SCADA (supervisory control and data acquisition), a category of software application program for process control, the gathering of data in real time from remote locations to control equipment and conditions. SCADA systems include hardware and software components. The hardware gathers and feeds data into a computer that has SCADA software installed, where it is then processed and presented it in a timely manner.
An IoT ecosystem consists of web-enabled smart devices that use embedded processors, sensors and communication hardware to collect, send and act on data they acquire from their environments. IOT Devices share the sensor data they collect by connecting to an IoT gateway or other edge device where data is either sent to the cloud to be analyzed or analyzed locally. The connectivity, networking and communication protocols used with these web-enabled devices largely depend on the specific IoT applications deployed.
