Fermion - ultrasonic sensor 15-900 cm - URM13 - DFRobot SEN0352

Index: DFR-19197 EAN: 5904422379322
Ultrasonic distance sensor equipped with URM13 chip. It can measure distances from 15 cm to 900 cm with an accuracy of 1 cm and a distance error of ± 1%. For communication it uses I2C and TRIG / UART (Modbus-RTU) buses, so it has more possibilities for real use and use in projects. The sensor features high measurement precision and maintains stable performance even in complex design scenarios.

Special features

  • Automatic noise detection and real-time calibration
  • Small and compact body, high sensitivity and measurement accuracy
  • Compatible with HC-SR04
  • It is recommended to use the sensor with a controller containing at least two serial ports
  • UART and I2C communication interface, RS485 extension support
  • Provides users with two measurement ranges to meet different application requirements:
    • short range from 15 cm to 150 cm with a detection frequency of up to 50 Hz, suitable for obstacle avoidance of indoor robots
    • long range from 40 cm to 900 cm with 10 Hz and high sensitivity, suitable for scenarios or projects in open terrain that require high accuracy and a large measuring range
    • sensing ranges can be triggered multiple times in real use to achieve full range measurements

Set contents

  • URM13 ultrasonic sensor
  • Goldpin terminal strip 1x4 pin - 2,54 mm

Leads description and example circuit diagram

The sensor has leads in a form of soldering fields, to which goldpin connectors should be soldered - 2,54 mm raster (an appropriate connector is included in the set). The sensor module is compatible with Arduino and Raspberry Pi boards. Connect the components according to the following relation:

  • VCC - power supply pin from 3.3 V to 5.5 V
  • GND - ground
  • C/T (UART-TX / I2C-SCL) - communication interface clock line (UART by default)
  • DR (UART-RX / I2C-SDA) - communication interface data line (UART by default)
  • EN (Power Enable) - power on pin
  • BUSY - control pin
  • ECHO - I2C signal output
  • TRIG - I2C signal input
