IoT Facts and Stats
Here are some intertesting facts about IoT:
- IoT is a key component of Industry 4.0. Industry 4.0, the Fourth Industrial Revolution, is the current trend of automation and data exchange in manufacturing technologies. It includes a number of new technologies such as the Internet of Things (IoT), robotics, 3D printing, and artificial intelligence (AI). This new era of industrialization is having a profound effect on all aspects of society, from the way we work and live to the way we interact with each other.
- The ATM, or automatic teller machine, is often credited as being the first widely used Internet of Things device. While the concept of connecting devices to the internet is now commonplace, this was not always the case. The ATM was developed in the early 1970s as a way to allow bank customers to access their accounts without having to visit a physical branch. To do this, the machine needed to be connected to the bank’s computer network. This required the use of new technology, which was not yet widely available. As a result, the ATM can be seen as an early pioneer of the Internet of Things.
- IoT devices come in all shapes and sizes. Some are small enough to fit in the palm of your hand, while others are as large as an industrial robot. The size of the device depends on the use case. For example, a small sensor might be used to track temperature or humidity, while a larger device might be used to control a machine in a factory. IoT devices can be used for a variety of purposes, so there is no one-size-fits-all solution.
- According to DataProt, there were over 10 billion connected IoT devices in 2021.
- By 2025, the number of IoT devices connecting to the internet per minute will exceed 152,200.
