While early scientists and inventors famously underestimated the value of radar, through the lens of history we can see how useful it became. Even though radar uses electromagnetic waves to detect ...

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 ...

There is a lot of buzz about electromagnetic (EM) detection and ranging sensor technology, which encompass radar, lidar, infrared (IR), ultra-wide bandwidth (UWB), and many others. However, there are ...

A salvaged Tesla Model 3 could detect distances even after the front bumper containing the ultrasonic sensors was taken off. This finding is surprising considering that the car was running the 2022.28 ...

Although ultrasonic sensors have been around for several decades, their popularity in sensing applications continues due to their capability, flexibility and relatively low cost. Products like ...

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 ...

Time-of-flight (ToF) sensors open up new application areas and use cases for proximity sensing and presence detection technologies, and these sensors can add valuable functionalities and intelligence ...

Consider scrapyards: These dirty outdoor environments are filled with objects of every shape, size, and material. Controls on machinery that manipulate scrap need sensors to detect when conveyor belts ...
