The Internet of Things (IoT) is defined as a network of physical objects or devices, including sensors, appliances, vehicles, or wearables, embedded with sensors, software, and other technologies. Such devices connect to the internet and collect, exchange, and analyze data without human intervention, thus making operations smarter and automated in different industries and daily life.
IoT devices function by collecting data through embedded sensors and then transmitting the data over the internet to a central server, cloud, or other devices for processing and analysis. The processed data can be used to take decisions, alert, or trigger actions automatically. A smart thermostat will collect data regarding room temperature and adjust the thermostat settings to create a comfortable environment.
Some common examples of IoT devices are:
