ADELPHI, Md. – Army scientists achieved a major milestone in quantum sensing technology that could transform how electromagnetic signals are detected on the battlefield. For the first time, scientists ...

Sony A7R cameras have always been more about resolution than speed, but with its latest model, the company has flipped that equation. The 67-megapixel A7R VI is not only Sony's highest-resolution ...

I’ve been writing about smoke detectors for a few years. That often involves researching fire statistics, so when I see something like the fact that the death rate from a fire is 60 percent lower in ...

Infrared sensors that detect the short-wave infrared (SWIR) region can clearly recognize objects not only during the day and at night, but also in fog or smoke, making them a key component of future ...

Chinese scientists have developed a new gravity-based detector that could be used to detect lurking submarines. Originally developed for scientific research and resource exploration, the device could ...

Flock license plate cameras tend to use rapid pulses (10hz: 20ms on, 80ms off) of 850nm IR light as part of the nighttime capture process. The strobe/capture process appears to be triggered by motion; ...

Variable reluctance (VR) sensors transform mechanical motion into electrical signals by exploiting changes in magnetic flux. As a ferromagnetic target moves past the sensor’s pole piece, the ...

The TCRT5000 sensor is an infrared reflective sensor. This library is written to use with a TCRT5000 breakout's analog output and handle a threshold in software. These breakouts have typical two ...

Abstract: The paper is the design and implementation of a lowcost vehicular speed detector system based on Arduino microcontroller along with the use of ultrasonic sensors. The suggested technology ...
