[Klaus] wanted some sort of aid for parking his car, and after running across a $4 ultrasonic sensor, decided to build his own speaking distance sensor (.de, Google Translation). Inside [Klaus]&#82… ...

The sensor also can be used in applications that require level sensing, such as in a liquid dispenser or coffee machine. The SmartSonic family of ToF sensors integrate a MEMS piezoelectric ...

The latter application pushed Tesla to develop new sensors, or new ways to hide the sensors, because CEO Elon Musk didn’t like the idea of a visible sensor in the middle of a door.

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.

On October 4th, Tesla announced that it plans to phase out ultrasonic sensors (USS) in favour of a camera-only ‘Tesla Vision’ driver assist system (via Electrek). This comes roughly a year and a half ...

One common technique used to eliminate cross talk is multiplexing. Multiplexing automatically staggers the ultrasonic bursts from each sensor such that no two sensors simultaneously send and receive.
