While the general principle of a radar is to emit a radio signal toward a target and analyze the reflected signal, there are different types. In continuous wave (CW ... the Passive Infrared (PIR) ...

This project can be used to control up to four industrial electrical appliances with the help of a joystick and an Arduino Nano board ... switch controlled by a standard passive infrared (PIR) motion ...

Image sensors are built into every smartphone and every digital camera. They distinguish colors in a similar way to the human ...

The Korea Research Institute of Standards and Science has successfully developed a high-quality compound semiconductor material for ultra-sensitive short-wave infrared (SWIR) sensors. The study is ...

Furthermore, we observe that the so far constant assumed factor to convert the sensor signal to the beam’s displacement depends on the dissipated power within the actuator, as well as on the dynamic ...

This study presents an advanced self-powered sensor for CO2 monitoring using surface acoustic wave technology, enhancing ...

While developing a vacuum system used for homemade PVD sputtering aparatus I felt the need of a simple and cheap vacuum gauge that can measure pressures as low as 1 Pa. I was not able to find online a ...

Abstract: Acoustic wave devices coated with a thin layer of chemoselective material provide highly sensitive chemical sensors for the detection and monitoring of vapors and gases. In this work, a ...

We aimed to develop and validate a novel custom-made transthoracic echocardiographic method for grading MR severity based on average pixel intensity (API) analysis of the continuous wave (CW) Doppler ...
