Arduino Based Gas Leakage Detection29 August 2023
A gas detector is a safety device that identifies the presence of gases in a particular location. It is often part of a safety system and can detect gas leaks and other emissions.
Introduction to TRIAC and TRIAC Dimmer10 September 2020
TRIAC is developed based on ordinary thyristors. It can not only replace two thyristors connected in parallel with reverse polarity, but also only needs one trigger circuit, which is an ideal AC switching device...
Buffer Amplifier | Operating Principle, Advantages, and Applications21 July 2025
This guide will talk in detail about the buffer amplifier to clarify all your concepts around its working principle and applications.
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.
How to Generate Negative Voltage: 5V to -5V Circuit Analysis & Schemes05 January 2026
Hello everyone, I am Rose. Welcome to the new post today. Today I will introduce negative voltage to you. Including its definition, how it was generated and its meaning.
How does an Inverter Work?06 April 2021
The inverter is a converter that converts DC electric energy into constant frequency and constant voltage AC or Frequency and voltage modulation AC. It is composed of an inverter bridge, control logic, and filter circuit. Inverters are widely used in air conditioners, home theaters, electric grinding wheels, power tools, DVDs, VCD, computers, TVs, washing machines, range hoods, refrigerators, video recorders, massagers, fans, lighting, etc.
What is a PIN Diode?04 February 2021
While diodes with a simple PN junction are by far the most common type of diode in operation, in a variety of applications, other forms of diode may be used. The PIN diode is one type that is used for a number of circuits. In a variety of places, this diode type is used. For RF switching, the PIN diode is very fine, and the PIN structure in photodiodes is very useful as well.
Top Chinese Photoresist Manufacturers Guide07 January 2022
Since the second half of 2020, the global semiconductor industry's prosperity has continued to rise, and the upstream photoresist market is no exception.
What are the Different Types of Fingerprint Sensors?16 December 2020
A fingerprint sensor is a key device to realize automatic fingerprint collection. Fingerprint sensors are classified into optical fingerprint sensors, semiconductor capacitive sensors, semiconductor thermal sensors, semiconductor pressure-sensitive sensors, ultrasonic sensors, and RF sensors according to the sensing principle.
MLCC: Applications and Future Development20 December 2021
MLCC is the abbreviation of Multi-layer Ceramic Capacitor. It is one of the main passive chip components in the electronic machine.
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.
What is an Accelerometer: Definition, Types and Applications02 April 2022
Hello everyone, I am Rose. Today I want to introduce the accelerometer to you. An accelerometer is an instrument that measures the linear acceleration of a carrier. An accelerometer consists of a proof mass (also called a sensitive mass), support, a potentiometer, a spring, a damper, and a housing. Among them, the accelerometer for measuring aircraft overload is one of the earliest aircraft instruments to be used.
