Ultrasonic sensors emit pulses, measure pulse travel time to calculate distance, used for displacement, thickness, distance, etc. URM06 Analog Ultrasonic Sensor detects 20cm~10m, compact PVC housing, 35mm pipe mount, analog interface, high acoustic power, 1cm resolution, 15° beam angle (excellent sensitivity), ideal for soft targets. Used in mobile robots (e.g., Pioneer). It’s the best in market for beam angle, sensitivity, accuracy.
