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
Sensors, as cutting-edge technology in modern science, are considered one of the three pillars of modern information technology and are recognized as a high-tech industry with great development potential both domestically and internationally. Sensor technology is directly related to the development of China’s automation industry. Experts believe that “if sensor technology is strong, then the … Read more

What is the Internet of Things? It can be understood as the internet that connects everything. To realize the functions of the Internet of Things, it still relies on the internet as the foundation and core, enabling information exchange and communication between objects. The application fields of the Internet of Things mainly include: transportation and … Read more
The Internet of Things (IoT) is an important component of the new generation of information technology and a significant development phase in the “information age.” As the name suggests, the IoT is an internet that connects everything. This has two implications: first, the core and foundation of the IoT remains the internet, which is an … Read more
The pace of development in China’s manufacturing industry is accelerating, and the number of industrial robots used in Chinese factories is increasing. To become a technical talent in industrial robotics, one must understand the internal structure of industrial robots. Below, we will introduce the structure of general industrial robots. First, let’s take a look at … Read more
This week, I will introduce you to a beautiful e-paper clock that also functions as a weather station (can automatically set via GPS). It can run for about 6 months on 4 AAA batteries, and to ensure safety and reliability, it does not require any network connection. Features include: Automatic setting (via GPS) Current temperature. … Read more
With the development of science and technology and research on nanotechnology, more and more nanotechnologies are transitioning from theory to practice. In daily life, the term “nanotechnology” is increasingly appearing in the public eye, from news media reports on cutting-edge nanoscience and nanoconcept products to the so-called nanoproducts in major shopping malls. Nanomaterials have a … Read more
To acquire information from the external environment, humans must rely on sensory organs. However, relying solely on human sensory organs is inadequate for studying the laws of natural phenomena and production activities. To adapt to this situation, sensors are required. Therefore, it can be said that sensors are an extension of human senses, also known … Read more
(⊙o⊙)…, I am sharing Arduino-related materials again. For some, it might be incomprehensible but impressive. But who told me I have been tinkering with Arduino recently~~~~ 1. Monochrome LED Module Figure 1 Monochrome LED Module Schematic As shown in Figure 1, RED corresponds to red, GRE to green, and BLU to blue, corresponding to digital … Read more
