With an internal temperature compensation and accurate distance detection, URM08-RS485 is a combination of temperature measurement device and distance inspection tool. The inner is fully enclosed and the external is made of metal crust, which has brought advantages such as waterproof, dustproof and corrosion resistance. It is applicable to detections of liquid level, levels, and barrier applications. As a high standard sensor, it guarantees smaller blind zones and larger inspection range. On the premise of stable output data, it shows better measurement capabilities in the market of temperature sensors and distance detection sensors.

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.
