The Sharp IR Range Sensor has been a pretty popular litle unit... Until now! The HC-SR04 is a very affordable and accurate little distance sensor. It uses ultrasonic sound waves to determine the distance of an object in front of it. The EZ-SDK and EZ-Builder both have support for the HC-SR04 sensor. Now add accuracy of 1 inch to your robot!
