How do Parking Sensors Work?05 August 2026
The parking sensor also called "parking aid", is mainly composed of ultrasonic sensors, controllers, and displays. It helps the driver "see" the invisible things in the rearview mirror, and inform the driver of the obstacles around the driver by sound or a more intuitive display.
Inverter Introduction: Structures, Working Principles and Features18 February 2022
Hello everyone, I am Rose. Today I will introduce inverter to you. The inverter is a converter that converts DC power (battery, storage battery) into constant frequency and constant voltage or frequency modulation and voltage regulation AC power (usually 220V, 50Hz sine wave).
How does a Resettable Fuse Work?26 August 2020
A resettable fuse is a kind of over-current electronic protection component. It is made of a high-molecular organic polymer under high pressure, high temperature, and sulfidation reaction. It's mixed with conductive particle materials, and processed by special technology.
What is ISP (Image Signal Processor)?15 September 2021
The ISP (Image Signal Processor) is mainly responsible for the photographing part in the system-on-chip (SOC) of the mobile phone.
Does the Terminal Resistance of the CAN Bus Have to be 120Ω?19 April 2022
Hello everyone, I am Rose. Today I will introduce Controller Area Network（CAN）to you. Knowing the function of terminal resistor will help us better understand causes of waveform instability and other problems in daily work.
Working Principles and Applications of Pressure Sensors07 April 2025
A pressure sensor is a device that can sense a pressure signal and convert the pressure signal into a usable output electrical signal according to certain rules. The pressure sensor usually consists of a pressure-sensitive element and a signal processing unit. According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors.
What is a Memory Controller?12 August 2020
The memory controller is an important part of the computer system that controls the memory and is responsible for data exchange between the memory and the CPU. The memory controller determines the maximum memory capacity that the computer system can use, the number of memory banks, memory type and speed, memory particle data depth and data width, and other important parameters. The memory controller determines the memory performance of the computer system and therefore has a greater impact on the overall performance of the computer system.
Introduction to DDIC (Display Driver IC)07 August 2026
Driver IC is an integrated circuit chip that controls the switching and display method of LCD panels and AMOLED panels. With the increase of panel display resolution and data transmission speed, the requirements for driver ICs are also increasing.
What Is a Safety Capacitor? Class X vs Class Y on the AC Line14 July 2026
A safety capacitor looks ordinary, but it does a job that an ordinary capacitor is not allowed to do: it connects directly to the AC mains and is built so that when it eventually fails, it fails in a way that does not put a person or the rest of the equipment at risk. That single difference, designed-in failure behavior backed by a certification standard, is what separates a "safety capacitor" from any other film or ceramic part with a high voltage rating printed on it.
LDR/Light Dependent Resistor: Working Principle, Types and Applications19 January 2026
In general, the control of lights and home appliances is manually operated and maintained on a number of occasions. However, due to the carelessness of human beings or unusual conditions, the process of controlling appliances may cause power wastage. We can use the light-dependent resistor circuit to control loads based on the intensity of light to overcome this problem. A device made of high-resistance semiconductor material is an LDR or a photoresistor. This article provides an overview of LDR, the light-dependent resistor circuit and its operation.
Working Principle and Types of Throttle Position Sensor01 April 2024
The throttle position sensor is also known as a throttle opening sensor or a throttle switch. Its main function is to detect the engine is in an idle condition or a load condition. It is an acceleration and reduction. It is essentially a variable resistor and several switches, mounted on the throttle
Nickel-Cadmium Battery: Construction, Features and Working Principle19 March 2026
A nickel-cadmium battery is a system that generates DC voltage by a chemical reaction between the components. In a nickel-cadmium battery, the redox material serves as the nucleus, with a nickel sheet and a separator surrounding it. The voltage of the nickel-cadmium cell is about 1.2 V. As three or four cells are connected in sequence, the output voltage ranges from 3.6 to 4.8 V.
