This URM12 - Ultra Long Range Ultrasonic Distance Sensor  from DFRobot delivers reliable distance sensing up to 15 meters. With a 15° detection beam, 3 Hz refresh rate, and Modbus‑RTU RS485 interface, the URM12 is tailored for industrial applications like tank level monitoring, water‑level measurement, or robot obstacle detection. It’s IP65‑rated, built to withstand dusty or damp environments, and supports 9–24 VDC power. The sensor offers 1 cm resolution at 1 % accuracy. Encased in a robust ABS shell, it ensures corrosion resistance and stable readings in harsh conditions.

Features:

  1. Ultra‑long detection range: 70 cm to 1500 cm
  2. High precision: 1 cm resolution and ~1 % accuracy
  3. Narrow 15° beam angle for focused sensing
  4. Fast update rate: up to 3 Hz
  5. RS485 interface with Modbus‑RTU support for industrial comms
  6. Operating voltage: 9–24 VDC, rated power 4.8 W
  7. IP65 protection for use in dusty or splashing environments
  8. Durable ABS housing offering corrosion and pollution resistance

Package Includes:

1 x DFRobot URM12 - Ultra Long Range Ultrasonic Distance Sensor (70~1500cm, RS485)

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
