REPLACED BY: DFRobot High Power Ultrasonic Range Finder V2.0 (SKU:SEN0003) URM05 High Power Ultrasonic Range Finder (SKU:SEN0003)

Overview

The DFRobot URM05 High Power Ultrasonic Range Finder is based on electrostatic senscomp's 6500 ultrasound transducer design. It can measure a distances of up to 10m. The angle between the ultrasound probes is only 15 °, while the majority of the ultrasound is 60 °.
