Learners in South Africa continue to shine during robotics and coding competitions against their international counterparts.

Sonair , previously operating in stealth, has revealed its innovative developments in sensor technology designed to improve safety in industrial automation. The company also announced the upcoming ...

Ultrasonic time-of-flight (ToF) sensors are embedding more powerful on-chip processors with higher computational capability to run a wide range of application algorithms while offloading the system ...

Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...

Reddam and Reddford learners have earned international honours for designing robots that tackle real-world issues, from ...

Ultrasonic sensors measure the distance between a target and the sensor using high-frequency sound waves that are inaudible to humans. The process is simple: the sensor emits ultrasonic waves, which ...

On November 5, 2025, in Beijing, China, @Lǎoxùdexiǎolú shared a video showing an autonomous delivery robot in action. In the ...

This post is a review of the popular waterproof ultrasonic sensor JSN-SR04T. I hope this will serve as a backdrop for some interesting ultrasonic distance sensor experiments and projects. A number of ...

But, similar bursts from other sensors in close proximity may interfere with the echo timing. When that happens, the sensors suffer from a condition called cross talk. Interference from cross talk ...
