What is a Sensor? A sensor is essentially a device or apparatus that can “convert physical quantities.” To obtain information for detection and control, it is necessary to convert the state, properties, and physical changes of an object into electrical quantities, using various physical laws for this conversion. Representative physical quantities that sensors detect and … Read more
First, let’s answer this question from the perspective of art installations. There are many tools or platforms involved in art installations, such as: Arduino, Raspberry Pi, 51 microcontroller, STM32 microcontroller, etc. Their advantage lies in the ability to DIY any installation, and many creative prototypes can be realized through different sensors.However, the devices mentioned above … Read more

7. Silicon Controlled RectifiersSilicon controlled rectifiers are an essential component of circuit boards, which is why enthusiasts love to use them. We also refer to them as thyristors because they are very similar to diodes and transistors. They consist of four layers of silicon and have only three leads; they are not used as amplifiers … Read more
I2C (Inter-Integrated Circuit) is a serial communication protocol used for short-distance communication, typically for data transmission between microcontrollers and various peripheral devices (such as sensors, displays, memory, etc.). Characteristics of the I2C Protocol The I2C protocol has several notable features: Two-wire Communication: The I2C protocol uses only two signal lines: SDA (data line) and SCL … Read more
The I2C bus is one of the most commonly used communication protocols in embedded systems, serving as a “dedicated highway” between microcontrollers and various sensors and memory devices. Today, let’s discuss how this protocol works and how to use it to read data from temperature and humidity sensors. I2C Protocol Basics The I2C protocol uses … Read more
……….. Comprehensive instruments are diagnostic devices that integrate multiple testing functions into one, making it more convenient for on-site fault diagnosis with multi-parameter detection. Currently, there are mainly six combinations of testing functions for such instruments: ① combination of pressure and flow; ② combination of pressure, flow, and temperature; ③ combination of pressure, flow, and … Read more
Introduction In industrial automation, analog signals are an important data type processed by PLCs, commonly found in measurements from sensors such as temperature, pressure, liquid level, and speed. Unlike digital signals that only determine ‘on’ and ‘off’, analog signals can represent continuous values. For example, the output from a temperature sensor may be a voltage … Read more
Hello everyone, I am Lao Wang, an experienced engineer in the automation industry. Today, let’s talk about PLCs, which are the core of the automation field, just as important as the light switch in our homes. However, instead of controlling a simple light bulb, it controls various complex industrial devices. The goal of this article … Read more
