In daily production and life, Ultrasonic ranging sensors are mainly used in automotive parking distance control (PDC), obstacle avoidance robotics, construction sites and industrial work environments where liquid level, well depth, pipe length, etc. are required with non-contact auto ranging. There are two commonly used methods for ultrasonic distance measurement. One is an ultrasonic ranging system based on single-chip microcomputer or embedded device, the other is an ultrasonic ranging system  ...

Warm hints: The word in this article is about 2500 and  reading time is about 12 minutes.SummaryFiber optic sensor consists of light source, incident fiber, exit fiber, light modulator, light detector and demodulator. The basic principle is that the light of the light source is sent to the modulation area through the incident optical fiber, and the light interacts with the measured parameters in the modulation area to change the optical property of the light into the modulated signal light  ...
Warm hints: The word in this article is about 2500 and  reading time is about 12 minutes.SummaryThis article focuses on GPS and inertial sensors for driverless applications. GPS is an indispensable technology for current driving location.But due to GPS error, multipathing and low update frequency, we can not rely on GPS for positioning. The inertial sensor has a high update frequency that can complement with GPS. Using sensor fusion technology, we can integrate GPS and inertial sensor data  ...
SummaryResearchers at TU Wien have succeeded in developing a method for the controlled manufacture of porous silicon carbide. Silicon carbide has significant advantages over silicon; it has greater chemical resistance and can therefore be used for biological applications, for example, without any additional coating required.Extremely fine porous structures with tiny holes – resembling a kind of sponge at nano level – can be generated in semiconductors. This opens up new possibilities for the rea ...
SummaryRihito Kuroda, a researcher at Tohoku University in Japan who develops UV imagers in his lab said“There's important information hidden in the UV,”. However, this information has been difficult to capture; silicon doesn't absorb ultraviolet wavelengths very well, and other semiconductors that play well with ultraviolet light make slow imagers with low frame rates. But that’s about to change. This week at the International Electron Devices Meeting in San Francisco, two research grou ...
SummaryIf you have follow the informations of sensor,you will know that sensors are always in a state of rapid progress.Now I will state a few things to prove it in the following.Sensor,also called Transducer, is a kind of detection device,it can receive the measured information and then output them according to a certain rule or other needed form to meet the transport, handling,storage,recording,displaying and controlling of imformation,etc. Know more about it,you can read the article : Most Co ...
SummaryEnergy-efficient sensor nodes are crucial to the development of the industrial internet of things (IIoT).Engineering team are trying to optimise energy efficient IIoT sensor nodes.In many cases, these devices will have to perform for years on a single battery charge. That calls for an implementation that is as energy efficient as possible. Achieving this demands a holistic approach to energy optimisation, one that reaches from the system level down to process and circuit-design choices.Pr ...
SummaryA digital temperature sensor IC which offers accurate measurements in the temperature range -20 to 10°C has been introduced by ams. The performance of the AS6200C makes it easier for designers of refrigerators and data loggers in cold-chain storage equipment to meet demanding targets for system-level accuracy. The AS6200C’s measurements are accurate to ±0.2°C between -20°C and 10°C, the temperature range over which storage equipment for perishable goods operates.AS6200C Sensor ICAS6200C s ...
SummaryResearchers at Caltech have developed a prototype miniature medical device that could ultimately be used in “smart pills” to diagnose and treat diseases. This is critical for the function of biosensors and smart pills. A key to the new technology—and what makes it unique among other microscale medical devices—is that its location can be precisely identified within the body, something that proved challenging before.The picture is about an ATOMS microchip localized within the gastroint ...
A while back,MEMS and Sensors Executive Congress that many designers,researchers and industry reoresentatives argued for putting MEMS devices such as accelerometers and microphones, and a wide variety of other sensors in just about everything was held in San Jose,Calif..We heard about an electric snowboard with traction control, voice-controlled garbage cans, and accelerometers placed on the nose to listen for speech in noisy environments.But sometimes the simplest example is the most memorable. ...
Two new 0°to 360°angle sensor ICs which can provide contactless high-resolution angular position information based on magnetic Circular Vertical Hall(CVH) technology has been introduced by Allegro MicroSystems, a leader in developing, manufacturing and marketing high-performance semiconductors.Called A1333 and A12339,the devices include a system-on-chip (SoC) architecture the involves: digital signal processing,CVH front end and supports multiple digital output formats as well as the first moto  ...
Do you know graphene? Graphene is made of a single layer of carbon atoms that are bonded together in a repeating pattern of hexagons,it is one million times thinner than paper,so thin that it is actually considered two dimensional. Nowadays more and more electronic components are made of graphene such as solar cells,transistors or transparent screens cause it can help computing performance continue to grow.After a brief introduction of graphene,let's go into the subject--graphene sensors.As  ...
