The DFRobot URM09 is an analog output ultrasonic distance sensor optimised for fast ranging and obstacle avoidance. With a maximum measurement rate of 30Hz, built-in temperature compensation, and a range of 2–500cm, it's a capable and easy-to-use sensor for robotics, automation, and detection projects.
The Gravity connector interface makes it plug-and-play compatible with DFRobot shields and boards, while the 3.3–5.5V operating range suits Arduino, Raspberry Pi, micro:bit, and most other platforms.

Jargon buster
Plain-language definitions for the technical terms used above.
- Gravity
- Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.
- Temperature compensation
- Temperature compensation means the sensor adjusts its readings to reduce errors caused by changes in water temperature. This matters for field monitoring because ponds, rivers, and tanks can vary in temperature throughout the day and across seasons.
