This sensor uses sound waves to measure the distance between the sensor and the obstacle. It works on the principle of Doppler effect.

Have you checked the beam width or the minimum/maximum distances it works at? Did you use an Arduino?</p><p>&nbsp;</p><p>Dubbie</p><img src="https://community.element14.com/aggbug?PostID=10929&AppID=293&AppType=Weblog&ContentType=0" width="1" height="1">
