An IoT ecosystem consists of web-enabled smart devices that use the embedded system, such as processors, sensors, and communication hardware to collect, send and act according to the data they acquire from their environments. IoT devices share the sensor data they collect by connecting to an IoT gateway or other edge device. Data is sent to the cloud and made to be analyzed or analyzed locally. Sometimes, these devices communicate with other related devices and act upon the information they get from one another. The devices do most of the work without human interaction, although people can interact with the devices – for instance, to set them up, give them instructions and access the data.
The connectivity, networking, and communication protocols used with these web-enabled devices are highly dependent on the specific IoT applications deployed.
IoT can also use artificial intelligence (AI) and machine learning to make data collecting processes easier and more dynamic.
