Nowadays, nearly everything around us — from animals and household lights to human beings and cars — has the ability to be brought online to interact with other machines.
This concept of physical objects communicating and interacting with each other online is referred to as the Internet of Things or IoT. This online network of physical objects is accomplished through the use of types of sensors, actuators and RFID tags.
Installing these tags inside a physical object gives it the ability to be monitored and controlled remotely through the Internet. This eliminates the need for humans to constantly enter and monitor data. Instead, objects can communicate directly with each other, without the need for a person to link them together.
