Introduction to Temperature Sensors24 October 2025
The temperature sensor refers to a sensor that can sense the temperature and convert it into a usable output signal, which is the core part of the temperature measuring instrument. It's divided into 5 types and each type has unique working principles. Besides, some factors need to be noticed in the installation and using process. For the temperature sensor can accurately measure the ambient temperature, it's widely used in various fields and provide convenience for people's production and daily lives.
Introduction to Types of Motion Sensors24 October 2025
Motion sensor refers to a device that detects the motion of an object or person, including gravity, linear acceleration, rotation vector, vibration frequency, etc. Motion sensors can be used to monitor device movements such as tilt, shake, rotation, or swing. Among them, the rotation vector sensor and the gravity sensor are the most commonly used sensors for motion detection and monitoring. Today we come to learn about various types of motion sensors, including accelerometers, tilt sensors, vibration sensors, PIR (passive infrared) sensors, and rotation sensors.
Bearing: Features, Types and Uses08 February 2022
Hello everyone, I am Rose. Today I will introduce bearing to you. Bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy.
What are Graphene Transistors?21 October 2025
Graphene is a two-dimensional crystal. Its structure is very stable because carbon atoms are arranged in hexagons and connected to each other to form a carbon molecule.
An Overview of Supercapacitors20 October 2025
Supercapacitors, also known as electrochemical capacitors, electric double-layer capacitors, gold capacitors, and farad capacitors, are developed between the 1970s and 1980s, which is an electrochemical element that uses polarized electrolytes to store energy. The supercapacitor is different from the traditional chemical power supply. It is a power supply with special performance between the traditional capacitor and battery, which mainly relies on the electric double layer and redox pseudo capacitor charge to store electrical energy. However, no chemical reaction occurs during the energy storage process. This energy storage process is reversible, for which supercapacitors can be repeatedly charged and discharged hundreds of thousands of times.
What is Vacuum Circuit Breaker?12 October 2021
Hello, I am Rose. Welcome to the new post today. The name "vacuum circuit breaker" comes from the fact that both the arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are high vacuum; it has the advantages of compact size, light weight, frequent operation, and no arc extinguishing maintenance. This article introduces basis knowledge about vacuum circuit breaker.
Solid State Relay Basics: Working, Features and Structure17 September 2020
Solid State Relay (SSR) is a non-contact switch composed of microelectronic circuits, discrete electronic devices, and power electronic power devices. The isolation device is used to realize the isolation between the control end and the load end. The input terminal of the solid state relay uses a tiny control signal to directly drive a large current load.
Basic Introduction to Hall Effect Sensors13 November 2025
The Hall effect sensor is a magnetic field sensor made according to the Hall effect. The Hall effect is a type of magnetoelectric effect. This phenomenon was discovered by Hall (A.H. Hall, 1855-1938) in 1879 when he studied the conductive mechanism of metals.
Design and Implementation of High Frequency Inverter for Printer Based on IR211013 April 2022
Hello everyone, I am Rose. Welcome to the new post today.In this article, the design of an independent inverter power supply based on SPWM technology is completed by combining the principle of the inverter circuit with the single-chip technology.
What is the Ripple of the Power Supply, How to Measure its Value, and How to Suppress it?23 November 2021
Hello everyone, I am Rose. Welcome to the new post today. Ripple is a multi-dimensional clutter signal. It's a periodic signal that varies up and down around the output DC voltage, but the period and amplitude aren't fixed, and the ripples of different power sources alter with time. In addition, the waveform is different.
