Stephen is an author at Android Police who covers how-to guides, features, and in-depth explainers on various topics. He joined the team in late 2021, bringing his strong technical background in ...

If you need to measure a distance, it is tempting to reach for the ubiquitous ultrasonic module like an HC-SR04. These work well, and they are reasonably easy to use. However, they aren’t without ...

The S80 Time-of-Flight Class 2 laser distance sensor features the ability to detect objects as small as 0.4mm. Time-of-Flight technology is based on the measurement of the time between the emission ...

CMOS image sensors have become a cornerstone of modern imaging, leveraging the advantages of low power consumption, high speed, and scalability inherent in complementary metal–oxide–semiconductor ...

Laser distance or displacement sensors use timeof-flight sensing to handle the positioning monitoring process. Time of flight (TOF) measures the time needed for a burst of laser light to travel from ...

Of course, many different types of distance measuring sensors exist but not all sensors are the same. Each sensor has its own advantages and disadvantages. At its most basic level, a distance ...

Every robotics project out there, it seems, needs a way to detect if it’s smashing into a wall repeatedly, acting like the brainless automaton it actually is. The Roomba has wall sensors, just about ...

The various ways your PC-screen “privacy” can be compromised. How a sensitive time-of-flight (ToF) transducer can be a critical privacy (and power-saving) building block. The many circumstances for ...
