What is an Accelerometer Sensor?20 April 2021
An accelerometer sensor is a sensor that can measure acceleration. It is usually composed of masses, dampers, elastic components, sensitive components, and adaptive circuits. In the process of acceleration, the sensor obtains the acceleration value by using Newton's second law, measuring the inertial force on the mass block. According to the different sensitive components of the sensor, common accelerometer sensors include capacitive, inductive, strain gauge, piezoresistive, piezoelectric and so on.
What is Universal Serial Bus (USB)?19 January 2026
Universal Serial Bus (USB) is a serial bus standard and a technical specification for input and output interfaces. It is widely used in information communication devices. The latest generation is USB4, and its transmission speed is 40Gbit/s, the three-stage voltage is 5V/12V/20V, the maximum power supply is 100W.
Introduction to Tantalum Capacitors16 October 2025
Tantalum capacitors are products with small volume, high capacitance and excellent performance. They were first developed by Bell Labs in the United States in 1956. They come in a variety of shapes and are made into small and chip components suitable for surface mounting, which are not only used in military communications, aerospace and other fields but also used in industrial control, film and television equipment, communication instruments and other products.
An Overview of Linear Integrated Circuits23 October 2025
A linear integrated circuit is an integrated circuit based on an amplifier. The meaning of "linear" used to indicate that the response relationship of the amplifier to the input signal is usually linear.In this essay, we’ll first introduce the development history of linear integrated circuit. And then the production process and the high-frequency technology are discussed in detail. The following two parts mainly talk about the linear integrated circuit types and forms. And the final chapter analyzes the two typical bipolar linear integrated circuit一 Lm386 and 34063.
What is an Inductive Sensor?31 October 2025
An inductive sensor is a device to realize non-electric measurement by using the change of coil self-inductance or mutual inductance. Using inductive sensors, displacement, pressure, vibration, strain, flow and other parameters can be measured. It has a series of advantages such as simple structure, high sensitivity, large output power, small output impedance, strong anti-interference ability, and high measurement accuracy, so it is widely used in the electromechanical control system.
Basic Introduction to Memristor12 January 2021
Memristor is a circuit device that expresses the relationship between magnetic flux and electric charge. The memristor has the dimension of resistance, but unlike resistance, the resistance of the memristor is determined by the charge flowing through it.
What is a 555 Timer?09 April 2025
555 Timer is an integrated circuit chip that is often used for timers, pulse generators, and oscillating circuits. 555 can be used as a delay device, a trigger, or a starting resonator element in a circuit.
What are the Types and Dielectric of Ceramic Capacitors?16 October 2025
A ceramic capacitor is also called a monolithic capacitor, whose dielectric material is ceramic. According to the different ceramic materials, it can be divided into two types: low-frequency ceramic capacitors and high-frequency ceramic capacitors. According to the structure, it can be divided into wafer capacitor, tubular capacitor, rectangular capacitor, a chip capacitor, feedthrough ceramic capacitor and so on.
Filters Explained: Principles, Parameters and Application Guide09 April 2025
A filter is a frequency selection device that allows specific frequency components to pass through while significantly attenuating other frequency components. This article provides a comprehensive introduction to the basic concepts, main parameters, classification, operating principles and precautions for the use of filters.
AC Contactor: What is Self-Locking?01 March 2022
AC contactors often use three arc extinguishing methods: double-break electric arc extinguishing, longitudinal seam arc extinguishing and grid arc extinguishing. It is used to eliminate the arc generated by the moving and static contacts during the opening and closing process.This article mainly introduce the principle of AC Contactor self-locking.
All You Need to Know about Ultrasonic Sensors25 October 2025
The ultrasonic sensor is a sensor that converts ultrasonic signals into other energy signals. It consists of 4 parts: a transmitter, a receiver, a control part, and a power supply. For ultrasonic probes that can be made from different materials, we should learn about their performances before usage, which includes the working principle, working process, sensitivity, and directivity. Based on the properties of ultrasonic waves, ultrasonic sensors are widely used in communication, medical, and home appliance.
What is a Force Sensor?19 April 2021
Force sensor (force sensor) is a component that converts the magnitude of force into related electrical signals. The force sensor can detect mechanical quantities such as tension, pressure, weight, torque, strain, and interior stress. It has become indispensable core component of power equipment, engineering machinery, various working machines, and industrial automation systems.
