The main technical basis of the Internet of Things is the Internet and microprocessor technology. Thanks to ever smaller microprocessors – which are also very powerful – objects can be equipped with electronic intelligence with very little effort. They also receive an interface for connection to the Internet and a unique Internet address. The devices can then send or receive data and commands via this address. RFID (radio frequency identification) technology plays an important role in the identification of goods and merchandise and their tracking in logistics. RFID systems consist of a transmitter, the transponder and a networked reader. The transponder is recognized and read wirelessly by the reader. The captured data is then forwarded via the web for further processing.
Microcontrollers are an essential part of most connected devices. In the future, these devices will support the implementation of millions of endpoints for the Internet of Things. Endpoints can be very different elements: Meters, sensors, displays, or preprocessors that combine multiple functions in a single device. A common requirement for IoT endpoints is to be as small as possible, as these components typically need to make do with very little space, but also to have low power consumption.
A typical example for the use of microcontrollers are wearable devices (smartwatch, data glasses): Here, a small format and low weight are crucial requirements for customer acceptance.
