Ultrasonics or ultrasound is a radar-like system that uses ultrasonic signals at frequencies above those typical for human hearing, usually above 16 to 20 kHz. The 40- to 70-kHz range tends to be most ...

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 ...

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 ...

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 ...

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 ...

Tesla moves to reliance solely on cameras for Autopilot operation, dropping ultrasonic sensors and radar. The automaker will leave some features disabled in new cars until cameras can replace the ...

Tesla announced removing ultrasonic sensors from its vehicles in October last year, promising that Tesla Vision would offer the same functionality. Nevertheless, despite some tentative moves, newer ...
