Most IoT applications require more than just adding a sensor to a physical object. When people talk about ‘smart objects,' they are usually talking about the addition of an Internet-connected microcontroller (also known as an MCU).
Microcontrollers can be thought of as tiny computers that are added to any physical object or space to give it a ‘brain.' They contain one or more computer processors, along with memory and programmable input/output peripherals — all in a single integrated circuit.
