With the rapid development of industrial automation, IoT devices, smart manufacturing, medical electronics, and intelligent monitoring systems, sensors and transducers have become essential components in modern electronic products. A sensor detects physical parameters from the surrounding environment, while a transducer converts these physical signals into electrical signals that can be processed by electronic circuits. In...
The SPI (Serial Peripheral Interface) is a widely used synchronous communication protocol in embedded systems, commonly applied for communication between: Microcontrollers (MCUs) Sensors Memory devices ADC/DAC converters Display controllers Communication modules Unlike protocols such as I²C, which use open-drain signaling and require pull-up resistors by design, SPI typically uses push-pull drivers. This leads to a...
With the development of smart agriculture and precision farming technologies, traditional irrigation systems are gradually being replaced by intelligent solutions that integrate wireless communication, environmental sensing, and automated control. A wireless smart irrigation controller is an important component in modern agricultural management systems. It enables remote monitoring, automatic irrigation scheduling, and optimized water usage based...
With the increasing adoption of distributed renewable energy systems, microgrids, and decentralized power generation, small wind turbines have become an effective solution for providing clean energy in residential, agricultural, and industrial applications.
