The RS485 interface allows a number of sensors to work together. Up to 32 URM04 may be connected together in a network.\u003c\/p\u003e\n\u003cp\u003eThe ultrasonic sensor allows you to determine the exact distance of an obstacle in the sonar field of view. The cleverness of your robot will depend on a sensitive sensor similar to the one bats use to know their position and track prey. With advanced programming, you can design compensators in order to perfectly control your motors according to the obstacle's distance.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: #ff0000;\"\u003eNOTE:\u003c\/span\u003e This sensor \u003cspan style=\"color: #ff0000;\"\u003eREQUIRES\u003c\/span\u003e an \u003cspan style=\"color: #ff0000;\"\u003eRS485\u003c\/span\u003e interface.
