Gravity: URM09 Ultrasonic Distance Sensor (2～500cm, Analog)

The Gravity: URM09 Ultrasonic Distance Sensor is an analog sonar module designed for fast distance measurement and reliable obstacle avoidance. Capable of detecting objects from 2cm to 500cm with built-in temperature compensation, it is well suited for students, educators, and hobbyists building autonomous mobile robots.

Fast 30Hz measurement frequency

Operating at a refresh rate of up to 30Hz, this sensor provides rapid response times for real-time collision detection. This high-speed capability makes it ideal for dynamic navigation and fast-moving robotic platforms.

Accurate 2cm to 500cm detection

The sensor measures distances from 2cm up to 500cm with 1cm resolution and 1% accuracy. Integrated temperature compensation ensures stable and precise readings across operating temperatures from -10 to +70 degrees Celsius.

Wide voltage logic compatibility

Supporting an input voltage of 3.3V to 5.5V DC with an operating current of 20mA, the module works with both 3.3V and 5V logic levels. It interfaces smoothly with Arduino, Raspberry Pi, and other standard microcontroller boards.

Compact format with analog output

Measuring 47mm by 22mm, the board easily mounts into space-constrained projects. It outputs a standard analog signal and includes a PH2.0-3P Gravity connector cable for straightforward wiring.
