is IoT? (IoT)
The word Internet of Things(IoT) should be
familiar for people.Automatic factory, smart city and smart appliances,
etc. all contain elements of IoT.
Simply put, the main concept is connect the device to network so that the device can communicate or transfer data to other device through network.
concept first appeared in 1982
It's a Coca-Cola vending machine, because students have to stay in the research room all day, sometimes thirsty and want to buy a glass of Coke, but when they walked to the vending machine far away, they realized that there was no Coke anymore. So smart students connect the vending machine to the Internet to monitor the amount of cola cans, and they can know whether the vending machine is still in stock in the research room. Also, because they are always recording the situation of the vending machine, this group of students know that the vending machine sells about 120 bottles of Coke every day.
term first appeared in 1999
term "Internet of Things" first appeared in 1999.
Proposed by Kevin Ashton of the Massachusetts Institute of Technology's Automatic Identification Center, he used this concept to describe how things change our lives when device connected to the Internet. With the passage of time, until the Industrial 4.0, the term IoT began to be widely used, and the slogan has been 10 years since 2011, and it is still under development and experimentation. Industry 4.0 emphasizes smart factories, which include device-to-device communication, and this is the concept of IoT.
How Does it Work?
As mentioned above, the concept of IoT is implement device-to-device communication, But how is it done?Let us split into the following questions:
When the device is equipped with temperature sensor, humidity sensor, pressure sensor, laser distance sensor, camera, etc., these messages can be received.
Through wired network or Wi-Fi, Bluetooth, ZigBee and other wireless communication technologies, these messages can be sent to the computer, and the computer can start to analyze the messages.
Then the computer can output information to user, such as the Coca-Cola vending machine of Carnegie Mellon University in 1982. Computers can also send control commands to devices through internet, such as smart appliances.
Architecture of Internet of Things
IoT with IADIY
For the perception layer of IoT, we provide a variety of sensor products, such as camera modules that provide device image vision functions, and laser sensors that provide device ranging functions. These products are commonly used in robotics, automation and smart home appliances.
For the application layer, we also provide IMX series embedded computers, which receive information from the sensing layer and execute calculations and control task.
Users can use our sensors and embedded computers to implement IOT applications. In addition, we also provide a complete set of solution services. If you have any needs, please contact us.
In addition to purchasing suitable hardware devices, software development is also an important part. For integrated development, ROS is one of the common and practical tools.
