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.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- 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 is when a sensor or instrument adjusts its readings to reduce errors caused by changes in temperature. This matters because a sensor's raw output often drifts as conditions warm or cool, so compensation keeps readings more consistent and accurate over time.
