The object detection depends on shape, size and orientation.Some ultrasonic sensors detect objects with max.capable to place objects within 5 mm more accurately.Suitable to detect objects which are more than 1 meter away.Ultrasonic sensor Infrared sensor Detection range On the other hand, IR sensors use Infrared light to determine whether or not an object is present. Ultrasonic sensors use sound waves (echolocation) to measure how far away you are from an object. ultrasonic sensors is the way in which the sensor works. The biggest difference between IR sensor vs. With Robot Inventor, we’re back to ultrasonic measuring. In MINDSTORMS EV3, LEGO decided to swap that for an infra-red proximity sensor. 51515 ultrasonic sensor LEGO MINDSTORMS NXT – the white-and-orange one – used to have an ultrasonic sensor for measuring distances. It will calculate the beacon’s proximity and heading (angle) based on the signal hitting the sensor.ĮV3 IR Proximity vs. Whereas the infrared sensor does do a couple of other cool things other than measuring distance: Beacon mode: in this mode it can detect an infrared beacon. The ultrasonic sensor’s primary purpose is to measure distances, it does however, have a listen mode which will listen for other ultrasonic sensors. In this program, the robot moves forward until the Wait block tells it to stop 25 units from a wall or other barrier. If you are using the IR sensor, it should be plugged into port 1 and this program is at the bottom line. If you are using the Ultrasonic Sensor, it should be plugged into port 4, and this program is on the top line.

We are going to start out with a simple program and will gradually add complexity to it. If you’re willing to compromise reliability for cost, infrared sensors are ideal for your application. If reliability is an important factor in your sensor selection, ultrasonic sensors are more reliable than IR sensors. Ultrasonic sensors work using sound waves, detecting obstacles is not affected by as many factors. With the sensors that come with the EV3, you can make a robot respond to being touched, react when someone or something comes too close, follow a line, or measure how far they have turned. Sensors provide robots with information about their environment.
