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 ...

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 ...

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 ...

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 ...
