The Internet of Things is the network of human-made physical devices, home appliances, cars, industry and other items that are connected to smart sensors, software, databases, electronics and network which allows all items to share collected data. The recent study shows that more than 193 million connected IoT home devices will be online by 2020. The IoT ability to collect and monitor data is the future key to improve daily human life efficiency.
The IoT brings new opportunities for data being collected and shared across network infrastructure, allowing devices to be controlled remotely by using a software or application The physical-world is transferred into a computing world, whereas much as possible human interaction is reduced. The major asset of IoT is to provide analysed data that can be used for further research or development. General benefits of IoT implementations in any industry are such as:
- Reduced costs
- Reduced errors
- Ability to forecast
- Improved productivity of the workforce
- Improved quality of product or service
The potential of a global market of IoT devices shows that every organization and the private person will own at least a single IoT device. According to Figure 1, the total number of IoT devices growth is predicted to be more than 75 billion by 2025.

A smart home is one of the IoT areas that incorporate automation equipment to supply residents with monitoring and full control over the home. In 2003 the Department of Trade and Industry presented the following definition for the smart home:
“A dwelling incorporating a communications network that connects the key electrical appliances and services, and allows them to be remotely controlled, monitored or accessed.”
