DFRobot URM15 – 75KHZ Ultrasonic Sensor Long-Range Ultrasonic Sensing With RS485 Interface For Accurate Distance Measurement (30-500cm)

Description: 

The DFRobot URM15 stands out as a robust and reliable ultrasonic ranging sensor, engineered for accurate distance measurements even in challenging environments. Its IP65-rated waterproof probe ensures dependable operation in dusty and wet conditions, expanding its applicability to a wide range of industrial and outdoor scenarios. This sensor provides precise distance readings within an effective range of 30cm to 500cm when tested against a flat surface.

Leveraging the widely adopted RS-485 interface and adhering to the standard Modbus-RTU protocol, the URM15 guarantees stable and noise-resistant data transmission, crucial for seamless integration into industrial control systems. The sensor's versatility is further enhanced by its support for easily modifiable slave addresses and serial communication parameters, simplifying deployment and allowing for flexible network configurations with various industrial controllers.

Accuracy is paramount, and the URM15 incorporates a valuable temperature compensation feature. Users have the flexibility to choose between utilizing an external temperature sensor or the onboard sensor to dynamically adjust measurements, effectively minimizing the influence of fluctuating ambient temperatures on the accuracy of the distance readings.

At its core, the URM15 employs a high-performance 75 kHz ultrasonic transducer with a 40mm diameter. This carefully selected transducer contributes to the sensor's relatively narrow measuring angle, enabling more focused detection and reducing the potential for interference from nearby objects. Furthermore, the 75 KHz frequency ensures high sensitivity, allowing for reliable detection of even subtle changes in distance. This combination of features makes the DFRobot URM15 an excellent choice for applications demanding both environmental resilience and precise distance measurement.
