The architecture of the Internet of Things is mainly divided into three layers:
1. Perception layer (Sensors and Sensor networks),
2. Network layer (3G/4G/5G communication network),
3. Application layer (cloud services for various applications).
Perception layer Mainly discusses various wired or wireless sensors (such as temperature, humidity, brightness, gyroscope, three-axis accelerometer, heartbeat, blood pressure, pulse, etc.) and how to construct sensor networks to transmit the data collected by the sensors It is a very challenging task for sensors to achieve low power consumption (high battery life), low cost, small size, long wireless transmission distance, etc. The network layer mainly discusses how to use existing wireless or wired networks to Effectively transmit the collected data, such as using existing 3G/4G wireless transmission technology, or future 5G wireless transmission technology, etc. The application layer mainly explores how various application fields use the results of big data analysis to provide feedback and Control sensors or controller adjustments, etc. Overall, the Internet of Things is a living ecosystem. Sensors collect data and transmit it back to the cloud processing center through mobile phones or other device networks. After analysis, the control information is It is passed back to the controller for various fine or delicate controls.
For an integrated development environment, code editing is not only the most basic and necessary function, but also an important part that directly affects the user's development experience. The main
Millimeter wave filter technology is an important part of achieving mainstream 5G wireless communications, but there are many difficulties in physical size, manufacturing tolerance and temperature sta
When developing 430 programs, IAR development tools and USB emulators are often used, which greatly facilitates development. However, if the IAR version is incorrect, your USB emulator may become a "b
