For a detection range of up to 2,000 mm, ultrasonic sensors can be as close as 8 m. Marcel Ulrich at Pepperl+Fuchs provided information for this column.

The ultrasonic sensor scans the bin’s contents to determine fill rate once per hour, while the motion and temperature sensors run all the time. Based on the default settings, the unit has a 10-year ...

Instead, it relies on an ultrasonic distance sensor to detect a hand (or foot) waved in front of the door. An Arduino Leonardo runs the show, sounding a buzzer when the ultrasonic sensor is triggered.

The USSM1.0 PLUS-FS time-of-flight sensor detects objects using ultrasonic waves and includes an integrated driver and signal processor. This signal-processing ASIC calculates signal propagation time ...

Tesla uses ultrasonic sensors as proximity sensors, for its Autopilot, and for its auto-presenting and Falcon Wing doors on the Model X.

As the latest batch of Android smartphones, the devices that will launch globally in 2025, start to launch in China, we’re seeing ultrasonic fingerprint sensors more broadly used.

Ultrasonic Fingerprint Sensor Using a Piezoelectronic Micromachined Ultrasonic Transducer Array Integrated with CMOS Electronics. Applied Physics Letters, 2015 DOI: 10.1063/1.4922915 ...

Ultrasonic speed and temperature sensor provides maintenance-free reliability all season long. AIRMAR, the company who invented the Smart™ Sensor, has raised the bar with a new ultrasonic speed and ...
