Vibration sensors are sensors for measuring, displaying, and analyzing linear velocity, displacement and proximity, or acceleration. Vibration — however subtle and unnoticed by human senses — is a ...

Shock and impact sensors are used to detect and record shock or impact to a product or package. Shock sensors represent a subtype of inertial sensors, which includes accelerometers and vibration ...

The Price to Earnings (P/E) ratio, a key valuation measure, is calculated by dividing the stock's most recent closing price by the sum of the diluted earnings per share from continuing operations ...

We liked the YoLink Smart Window Door Sensors, LoRa ¼ Mile Range best and were impressed with its ability to transmit up to a quarter of a mile away. The best alarm for a particular shopper will ...

Both sensors measure rate of change; they just measure the rate of change for different things. In practice, that means that an accelerometer will measure the directional movement of a device but ...

Just like smartphone cameras, these sensors have a finite resolution. The higher the resolution, the finer details the sensor can discern about your finger, increasing the level of security.

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level ...

But a push to develop and deploy quantum sensors for navigation as a more accurate, less vulnerable alternative to GPS could change things. “In order to really succeed, we have to build the ...

Wearable sensors can expedite personalized medicine by integrating sensors into our daily lives. This Perspective discusses mechanical and electrochemical sensors, including their operating ...
