What is RFID?23 March 2021
RFID is the abbreviation of Radio Frequency Identification. The principle of RFID is to carry out non-contact data communication between the reader and the tag to achieve the purpose of identifying the target. RFID has a wide range of applications. Typical applications include animal chips, car chip anti-theft devices, access control, parking lot control, production line automation, and material management.
Working and Types of Touch Screen20 March 2021
A touch screen is an inductive liquid crystal display device that can receive input signals such as contacts. When the graphic buttons on the screen are touched, the tactile feedback system on the screen can drive various connected devices which can be used to replace mechanical button panels, and use liquid crystal display screens to create dynamic audio-visual effects.
What is an Optical Sensor?19 March 2021
An optical sensor is a sensing device applied to measuring tools. The optical sensor uses the optical principle of the sensor for measurement, and in the process of using the optical sensor, because the measurement is not contacted, and it will not cause damage on the scene during the measurement. Therefore, the measurement of the optical sensor is very accurate, and it is hardly interfered by other factors.
Introduction to FinFET18 March 2021
The full name of FinFET is Fin Field-Effect Transistor. It is a new complementary metal oxide semiconductor transistor. The FinFET name is based on the similarity between the shape of the transistor and the fin.
What is a Synchronous Motor?16 March 2021
A synchronous motor is an AC motor that generates torque by the interaction of the excitation magnetic field supplied by a direct current and the rotating magnetic field of the armature, and rotates at a synchronous speed.) is an AC motor that generates torque by the interaction of the DC-powered excitation magnetic field and the rotating magnetic field of the armature, which rotates at a synchronous speed.
What is OLED?16 March 2021
OLED (Organic Light-Emitting Diode), is also known as organic electric laser display, organic light-emitting semiconductor. OLED is a kind of current-type organic light-emitting device that produces luminescence through the injection and recombination of carriers, and the luminous intensity is proportional to the injected current.
VRLA Battery: Working Principle, Capacity and Maintenance12 March 2021
VRLA batteries, which means Valve Regulated Lead Acid Battery was born in the 1970s. By 1975, a considerable scale of production had been formed in some developed countries, and industrialization was soon formed and put on the market in large quantities. Although this battery is also a lead-acid battery, it has many advantages compared with the original lead-acid battery, and is very popular with users, especially for those who need to install battery supporting equipment together (or a workshop). , Such as UPS, telecommunications equipment, mobile communication equipment, computers, motorcycles, etc.
Introduction to STM32 Microcontrollers12 March 2021
The STM32 series is based on the ARM Cortex-M3 core specially designed for embedded applications that require high performance, low cost, and low power consumption. This article introduces the definition, types, difference between the STM32 microcontroller and 51 microcontrollers as well as the basic system of STM32.
What is a High-pass Filter?10 March 2021
A high-pass filter is a combination device of capacitors, inductances, and resistors that allow signal components above a certain frequency to pass, while greatly suppressing signal components below that frequency. The high-pass filter only attenuates the frequency components below a given frequency, and allows the frequency components above the cutoff frequency to pass, and there is no phase shift filtering process. Mainly used to eliminate low-frequency noise, also called low-cut filter.
What is a Servo Motor?09 March 2021
Servo motor refers to the engine that controls the operation of mechanical components in the servo system and is a motor indirect speed change device. The servo motor can control the speed and position accuracy very accurately and can convert the voltage signal into torque and speed to drive the control object.
Introduction to Reluctance Motor08 March 2021
This is a kind of advanced motor that, like a regular electric motor, has both a stator and a rotor. This motors use a direct spinning magnetic field (RPM) to synchronize the rotor's speed with the stator's RMF. These motors offer a high power density at a low cost, making them appealing in a variety of applications. The reluctance motor's operating theory is that if a magnetic material is placed inside a magnetic field, it often pulls itself into line in the least reluctance manner.
What is Solid-state Battery08 March 2021
A solid-state battery is a battery that uses solid electrodes and solid electrolytes. Solid-state batteries generally have low power density and high energy density. Because of the relatively high power and weight of solid-state batteries, it is an ideal battery for electric vehicles.
