1. Synchronous and Asynchronous Transmission 1.1 Concepts and Examples Using everyday examples to illustrate what synchronous and asynchronous mean: Synchronous: A friend calls to say they are coming to my house for dinner, and I wait for them at home. Asynchronous: A friend arrives at my house unexpectedly without prior notice. The difference lies in … Read more
Abstract: This paper proposes a design method and specific implementation plan for a control system based on dual STM32 chips. The control system uses two STM32F107VCT6 chips as master and slave controllers, communicating via a high-speed SPI interface to ensure real-time performance during the control phase. The hardware layout of the system is introduced, and … Read more

Among various sensing technologies, the most commonly used and widespread method for detecting magnetic fields is the Hall effect method. Based on the Hall effect, many Hall effect sensors or transducers have been found in various applications, primarily used for sensing proximity, speed, current, and position. This is due to the ability to construct Hall … Read more
Smart sensors are sensors with information processing capabilities. They are equipped with microprocessors and have the ability to collect, process, and exchange information, representing a combination of sensor integration and microprocessor technology. Compared to general sensors, smart sensors have the following three advantages: high-precision information collection through software technology, low cost; certain programming automation capabilities; … Read more

1. Working Principle of Sensors A sensor is a device that converts non-electrical quantities into electrical quantities. The non-electrical quantities sensed typically include pressure, temperature, displacement, concentration, speed, pH, etc. The output is usually an electrical quantity, such as voltage, current, or charge. These output signals are very weak and usually need to be amplified … Read more
