This URM12 from DFRobot is a long range ultrasonic distance sensor designed for distance ranging or obstacle avoidance applications. The sensor offers up to 1500cm detection distance, 3Hz measuring frequency and 15° detection angle. It adopts RS485 communication interface and supports standard Modbus-RTU communication protocol, which is suitable for level measurement, robot obstacle avoidance and so on.

What is the URM series?

The URM series is a range of ultrasonic distance measurement modules specifically designed for industrial control and robot control applications. These modules are equipped with internal temperature compensation functionality, allowing for accurate measurement of the distance between the sensor and the target object. They can be widely used in various scenarios, such as robot barrier navigation, liquid level detection, and obstacle avoidance designs.

Since the introduction of the first URM module in 2009, DFRobot has continuously released many models of the URM series of ultrasonic distance measurement modules. These modules cover a wide range of measurement distances, beam angles, accuracy levels, and interface options, catering to the requirements of different application scenarios.
