When coupled with the NXT Intelligent Brick, this ultrasonic sensor is able to detect an object and measure its proximity in inches and centimetres.

It helps your robot judge distances and see where objects are, so you can programme it to undertake cool operations!

  • Make your robot avoid obstacles, sense and measure distance, and detect movement
  • Uses the same scientific principle as bats, it measures distance by calculating the time it takes for a sound wave to hit an object and return

Suitable for Key Stages 2, 3 & 4 (ages 7 to 16). This is an individual component, and does not include any motors, cords, software or other accessories.
