A sensor (English name: transducer/sensor) is a detection device that can sense the information being measured and can convert the sensed information into electrical signals or other desired forms of information output according to certain rules, to meet the requirements of information transmission, processing, storage, display, recording, and … Read more
Sensors are devices designed based on the physical, chemical, and biological properties and laws of materials. There are various types, and in the measurement and control field, a sensor designed based on a certain principle can simultaneously measure multiple non-electrical quantities. Sometimes, a single non-electrical quantity can be measured by various sensors based on different … Read more
Author | Sensor Technology (WW_CGQJS) Introduction: With the development of sensors, miniaturization, intelligence, and integration have become essential for upgrades. Today, we will introduce a mini product from the sensor family – MEMS Sensors. What are MEMS Sensors? MEMS stands for Micro-ElectroMechanical System. A micro-electromechanical system refers to miniature devices or systems that can be … Read more
Everyone · Technology Frontier Li Bo Professor at the College of Physics and Electronic Science, East China Normal University, PhD Supervisor When we go shopping, many stores have automatic doors that open to welcome customers; faucets in restrooms automatically dispense water when needed, creating a more hygienic environment; smoke detectors tirelessly monitor for potential dangers … Read more
1. Bandwidth Generally refers to the range of signals where the sensor output response decreases to the square root of one-half of its maximum response or half of the power. Simply put, it indicates the range that the sensor can sample, and the bandwidth is the indicator of the sensor’s response range to external signals, … Read more
This machine was repaired with the assistance of one of our students, who reported that the machine had no no-load voltage. This is a single-phase 220 single board IGBT machine. We first disconnected the high voltage and applied 310V. We measured the drive waveform of the tube using an oscilloscope and found none. Next, we … Read more
