Introduction to Bandstop Filter28 January 2021
There are numerous filter types, including high-pass filters, low-pass filters, bandpass filters, and filters for bandstops. The high-pass filter only allows frequencies greater than the cut-off frequency, and the low-pass filter allows frequencies smaller than the cut-off frequencies. A specific band of frequencies will be permitted by the bandpass filter and a band stop filter will reject a specific band of frequencies. An overview of the bandstop filter is discussed in this article.
How does Lidar Work?20 April 2021
Lidar or LiDAR is an abbreviation for Light Detection and Ranging. Lidar is a radar that uses a laser as a radiation source. Lidar is the product of a combination of laser technology and radar technology.
Introduction to AC motor05 March 2021
The motor which uses an electromagnetic induction phänomen to convert the alternative current into mechanical power is called an AC motor. An alternating current drives this motor. Two main components of the AC motors include the stator and the rotor. The stator is the motor's permanent component, and the rotor is the revolving part of the motor. The AC motor can be single or 3-phase.
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.
An Overview of Photoelectric Sensors27 October 2025
The photoelectric sensor is a key component of photoelectric conversion in various photoelectric detection systems. It is a device that converts optical signals (visible and ultraviolet laser light) into electrical signals. There are many types of photoelectric sensors that use photoelectric elements as sensitive elements, and they are widely used. Photoelectric devices include photocells, photomultiplier tubes, photoresistors, photodiodes, phototransistors, photocells, etc.
Introduction to Step-down Transformers14 October 2020
The step-down transformer is a transformer that converts the higher voltage at the input terminal into an ideal low voltage output, so as to achieve the purpose of step-down. The step-down transformer is a very important equipment in the power transmission and transformation system. Its normal operation not only relates to its own safety and reliable power supply for users, but also directly affects the stability of the power system...
Infrared Thermometer: How it Works? How to Use it?12 August 2021
Infrared thermometers are divided into fixed thermometers and hand-held thermometers. They are a kind of thermometer that detects the amount of infrared rays on the surface of an object to achieve temperature measurement.

Toroidal transformer: Principles, Features, Types and Applications13 November 2020
Toroidal transformer is a type of electronic transformer, which has been widely used in household appliances and other electronic equipment with high technical requirements. It’s mainly used as a power transformer and isolation transformer, also widely used in computers, medical equipment, telecommunications, instruments and lighting. The toroidal transformer is a competitive electronic transformer for its good output characteristics and anti-interference ability.
What is a Voltage Controlled Oscillator?09 January 2026
Voltage controlled oscillator (VCO) refers to an oscillator circuit whose output frequency corresponds to the input control voltage. The operating state of the oscillator or the component parameters of the oscillation circuit are controlled by the input control voltage. The frequency of the VCO has a linear relationship with the control voltage. It is an important part of PLL.
Introduction to Silicon Controlled Rectifier25 September 2020
Silicon Controlled Rectifier, abbreviated as SCR, is a high-power electrical component, also known as a thyristor. It has the advantages of small size, high efficiency and long life. In the automatic control system, it can be used as a high-power drive device to realize the control of high-power equipment with low-power controls. It has been widely used in AC and DC motor speed control system, power control system and servo system.
