The term "Internet of Things" (or IoT) refers to a network of everyday things connected to the Internet, (usually home appliances), and connected to other devices as well, such as smartphones and tablets, and connected to each other as well. Typically, these things (devices) have some form of advanced technology inside them to help them not only connect to this network, but to interact with and respond to the environment in which these things are.
How does the "Internet of Things" technology work?
Any "Internet of Things" system consists of four main parts:
Sensors and devices.
Connectivity.
Data Processing.
User Interface.
The first part includes the sensors or devices that should collect information from their external environment. For example, a smart thermostat might receive a reading of your home's temperature.
In the second step (the second section) of this system (communication), this information is sent to the cloud through any type of Internet connection, such as "Wi-Fi".
After sending the data to the cloud, the third step is to process that data. During the data processing stage, the information must be analyzed to see if this data matches certain criteria.
The final step in the "Internet of Things" system is the user interface. After analyzing the data, the user interface of the IoT device will either make automatic adjustments to the IoT device to respond to the needs of the environment in which the “Internet of Things” device is located, for example: A smart thermostat (an example of an IoT device) may ) Automatically adjusts the temperature for your home, or it may send an alert on the smartphone to the user to let him know that the temperature is too high and ask him to set the temperature remotely.
Common IoT devices to be aware of:
The Internet of Things is a complex network of smart home devices, the Internet and us. We still have a long way to go in developing IoT technology, but this form of technology is undoubtedly beneficial, as it allows us to automate even the most common household tasks.
Let's take a look at some of the most used IoT devices.
1. Amazon Echo smart speakers:
Amazon's popular smart speaker (called Echo) controlled by voice commands can answer questions, play music on demand, control other smart home devices, set alarms, read news, and even make hands-free phone calls. All this is done by speaking by giving this smart speaker direct voice commands with your own voice.
2. Philips Hue automated home lighting:
The “Phillips Hue” is a smart home lighting system that involves the use of smart light bulbs, and contains a “smart hub” called “Hue Bridge” that connects the bulbs to your mobile device, and the “Hue” app. For smartphones who control the lighting of your home through your smartphone. A smart home hub is the device or software that connects devices on the smart home control network and controls communications between them. Smart home hubs, which connect locally or to the cloud, are useful for Internet of Things (IoT) devices that use Zigbee, Z-Wave, or Bluetooth protocols to communicate, rather than Wi-Fi.
3. The smart thermostat, "Google Nest":
Google's smart thermostat, Nest, customizes and controls your home's temperature. This thermostat learns your schedule so it is able to develop the optimum temperature settings in your home based on the current time.
4. Smart doorbells with Ring technology:
Ring devices - smart door bell devices - connect to your smartphone or tablet device through an application that alerts you when there is someone at your door, shows you through the camera who is the person standing at your door, and allows you to have a video chat with guests upon their arrival Through the camera and microphone inside the device.
Although we have focused on the consumer aspects of the average user of IoT, this branch of applied engineering is more important in the corporate sector.
