As you’re searching for the  sensor for your application.  You’ll find that you need to select a sensor that best suits your needs for your project. 

With that being said, our sensors operate well in different autonomous navigation and obstacle detection applications.

How Ultrasonic Sensors Work

Ultrasonic sensors work by sending out a sound wave at a frequency above the range of human hearing.  

The transducer of the sensor acts as a microphone to receive and transmitter to send the ultrasonic sound. 

Our ultrasonic sensors, like many others, use a single transducer to send a pulse and to receive the echo.  The sensor determines the distance to a target by measuring time lapses between the sending and receiving of the ultrasonic pulse.  The sensor is able to detect the presence of nearby objects without any physical contact.

Common uses include:

  • Robot ranging
  • Proximity zone detection
  • Autonomous navigation
  • Multi-sensor arrays

Our ultrasonic sensors are easy to install and low maintenance. They are intended for non-contact sensing.

Many of our lines work well to detect objects that may be directly in front of the sensor during power up.
