DFRobot URM14 RS485 Precision Ultrasonic Sensor(200KHz) is a high-frequency precision ultrasonic sensor for industrial use. The sensor measurement and signal processing unit is completely encapsulated in an M18 metal shell and its tail is designed with an aviation connector plug. The sensor uses the RS485 interface that follows the standard Modbus-RTU communication protocol, which assures its compatibility with PLC industrial personal computer. Furthermore, the adoption of higher ultrasonic acoustic frequency and more precision signal processing circuit gives this URM14 sensor mm-grade accuracy and up to1.5m reliable measuring range. The only 12° measuring angle makes the sensor able to present the directional measurement characteristic similar to laser ranging sensors.
With the advanced auto noise detection function integrated, the URM14 sensor can detect noise in real-time and adjust its parameter based on the noise level. In addition, it comes with a flexible temperature compensation function that allows users to use the sensor built-in temperature compensation or external temperature compensation according to their needs, which makes it applicable to various complicated application scenarios.

Jargon buster
Plain-language definitions for the technical terms used above.
- ModBus-RTU
- ModBus-RTU is a common industrial protocol for sending sensor readings and control commands over serial links such as RS485. Knowing the sensor uses ModBus-RTU helps you choose software libraries, data loggers, or controllers that can request and interpret its readings.
- RS485
- RS485 is a robust wired serial communication standard often used in factories, farms, and buildings where cables may be long or electrically noisy. It matters because it lets this controller connect to industrial sensors, meters, and control equipment over longer distances than typical hobby serial wiring.
- Temperature compensation
- Temperature compensation means the sensor adjusts its readings to reduce errors caused by changes in water temperature. This matters for field monitoring because ponds, rivers, and tanks can vary in temperature throughout the day and across seasons.
