Funktioner

Den digitale EV3 ultralydssensor genererer lydbølger og opfanger deres ekkoer for at registrere og måle afstande til objekter. Den kan også sende enkelte lydbølger, der fungerer som en sonar, eller lytte efter lydbølger, der udløser åbningen af et program. Elever kunne f.eks. designe et trafikovervågningssystem og måle afstandene mellem bilerne. De kan også få mulighed for at opdage, hvordan teknologi anvendes i hverdagssituationer, f.eks. automatiske døre, biler og produktionsmaskiner.

  • Målerafstande på 1-250 cm
  • Fejlmargin: +/-1 cm
  • Konstant frontbelysning; blinker i lyttetilstand
  • Returnerer sandt, hvis anden ultralyd registreres
  • Auto-id er integreret i EV3 softwaren

    ITS NOT ACCURATE
    | 14-18
    I'm doing some fll stuff and I need an ultrasonic sensor but when my parents purchased it I tried programing it and used online tutorials and stuff but IT DOESN'T WORK!! They even shipped me a brick from a totally different series! WHAT?! When I put my hand near it the thing reads 255 cm!! I try having it stop when it reaches a place but as long as its a tiny bit off it doesn't work. Both "eyes" have to detect the thing so you have to be crystal clear. Also, the gyro sensor turns 90 degrees when you set it to 80.

    Not as accurate as the product specification
    | 35-44
    Jeg vil anbefale denne til en ven!
    I just got this and I found that it doesn't live up to the specification. It seems like it can only work with 1 inch distance to 100 inch distances. It doesn't work with 1 cm distance as mentioned in the spec "Measures distances between one and 250 cm (one to 100 in.) ". Also, less than 1 cm actually reads back as 255 cm.

    Really usefull stuff!

    Jeg vil anbefale denne til en ven!
    If you bought the EV3 home set, then buy this sensor with it. It's so usefull for a lot of things. I know the IR-Sensor can do this too but it can't do it well enough because it's not made for doing this! Really get this thing because you are going to love it!!!!
