/products/arduino/arduino-projects/b/blog/posts/an-arduino-based-radarI recently came across this &quot; Instructable &quot; in which the user ahmedelsayed93 has created a project to detect obstacles in front of an ultrasonic sensor using Arduino Uno board. What is so great about it you ask, the video shows the ultrasonic sensoren-USTelligent Community 12https://community.element14.com/products/arduino/arduino-projects/b/blog/posts/an-arduino-based-radarMon, 28 Sep 2015 13:58:26 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:d4892209-807a-4876-b1a5-212f0e3f3629madhugovindarajan0<p>Hi DAB - I am guessing the range is limited by the sensor being used and not the scan speed. Most ultrasonic sensors operate at very high frequencies and should not be an issue.&nbsp; </p><img src="https://community.element14.com/aggbug?PostID=527&AppID=149&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/products/arduino/arduino-projects/b/blog/posts/an-arduino-based-radarFri, 25 Sep 2015 19:11:59 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:d4892209-807a-4876-b1a5-212f0e3f3629DAB0<p>Nice demo.</p><p>&nbsp;</p><p>It looks like the range is a bit limited.</p><p>&nbsp;</p><p>About how far away can the sensor detect objects?</p><p>&nbsp;</p><p>Is the current limitation based upon scan speed?</p><p>&nbsp;</p><p>Thanks</p><p>DAB</p><img src="https://community.element14.com/aggbug?PostID=527&AppID=149&AppType=Weblog&ContentType=0" width="1" height="1">
