What is a Microcontroller?30 October 2025
A microcontroller is a sophisticated single-chip microcomputer that integrates all essential computing elements onto a single integrated circuit (IC). Microcontrollers are mainly used for automatic control equipment in the fields of automobile air conditioning and automatic machinery. Microcontrollers are widely used in various industrial and civil embedded systems due to their small size, low power consumption, and ease of use.
Function and Application of Laser Sensors28 October 2025
Laser sensors are sensors that use laser technology for measurement. It consists of laser, laser detector and measuring circuit. The laser sensor is a new type of measuring instrument.
What is a USB Type-C Connector?28 October 2025
The USB connector has three interfaces with different appearances, namely Type-A, Type-B, and Type-C. A Type-C connector has a much smaller volume than Type-A and Type-B and is the latest USB interface appearance standard. Also, Type-C is an interface type that can be applied to both PCs (master devices) and external devices (slave devices, such as mobile phones).
Introduction to Wearable Sensors27 October 2025
A wearable sensor is the core of the wearable device which is a computing device that can be installed on people, animals, and objects, and can sense, transmit, and process information. The sensor in the wearable device is an extension and enhancement of the human senses.
Car Sensors: Classification and Application27 October 2025
The car sensor is the input device of the automotive computer-controlled system. The earliest car sensors are oil pressure sensors, oil quantity sensors, and water temperature sensors connected to instruments or indicator lights in the 1960s. There are many kinds of car sensors like temperature sensors, pressure sensors, flow sensors, etc., and they are applied in different applications according to their specific properties.
What are Smart Sensors?27 October 2025
Smart sensors are sensors that can automatically collect, process, and self-diagnose and adapt to information from the outside world. Smart sensors can store various physical quantities detected and process the data according to instructions to create new data.
Working Principle and Application of Infrared Sensors27 October 2025
The infrared sensor is a sensor used to detect infrared radiation. It mainly has 6 performance parameters including voltage response, response wavelength range, noise equivalent power(NEP), detectivity, specific detectivity, and time constant. There are generally 2 types of infrared sensors, thermal sensors, and photonic sensors. The 2 types have specific working principles but they're both based on the basic law of infrared radiation. And according to the application functions and places, infrared sensors are mainly used in radiation and spectrum measurement, search and track systems, and thermal imaging systems.
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.
How do Inductors Work?27 October 2025
Inductors are energy storage elements that convert electrical energy into magnetic energy for storage. It is similar to a transformer, but the inductor has only one winding. The structure of an inductor is generally composed of a skeleton, a winding, a shield, the packaging material, an iron core, and a magnetic core.
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.
Image Sensor: How do CCD and CMOS Sensors work?24 October 2025
An image sensor is a semiconductor device that can convert optical images into digital signals. It is widely used in digital cameras and other electronic optical devices. The image sensor uses the photoelectric conversion function of the photoelectric device to convert the light image on the photosensitive surface into an electrical signal in a proportional relationship with the light image. There are two kinds of image sensors which are CMOS and CCD. CCD and CMOS have their advantages in different application scenarios.
What is a Vibration Sensor?24 October 2025
The vibration sensor is used to detect the impact force or acceleration of the sensor. It usually uses piezoelectric devices which will generate charge under a stress. The vibration sensor can be used for long-term monitoring of vibration and displacement, thermal expansion amount of rotor, and chassis.
