Ultrasonic sensors use sound waves above 20 kHz to measure the distance from the sensor to a specified target. The sensor transmits and receives sound via a ceramic transducer that acts like a ...

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 ...

TDK Corp. has announced distribution availability of its second-generation InvenSense SmartSonic ICU-10201 ultrasonic time-of-flight (ToF) sensor for IoT and robotics applications. With improved ...

For years, ultrasonic sensors have been used in a wide range of applications including fish finders, parking sensors in cars and burglar alarms. In this article, we describe the characteristics of ...

Ultrasonic sensors can measure distance without contact. can measure distance without contact. They bridge the gap between proximity and photoelectric sensing. They possess a longer sensing distance ...
