More info

The TeraRanger Duo is a fully­calibrated distance­-measurement sensor that combines infrared Time­of­Flight (ToF) with ultrasound technology to detect any surface.

The sensor is simple to connect and use with one of its interfaces: UART, SPI or I/O, plus USB by using our adapter. It just streams out digital values in mm for both sensors ­ simple! There is a driver already available for ROS (Robot Operating System).

In addition, the TeraRanger Duo’s on­board processor has user space available if you would like to modify the output protocol or implement your own algorithm (please request the SDK in case).


  • Maximum reading frequency: 1000 Hz (ToF), 10 Hz (sonar)
  • Range: 0.2 - 14m (ToF), 0.05 - 7.65m (sonar)
  • Weight: 16 g
  • Dual technology: infrarred ToF + Ultrasounds
  • 100% eye safe
  • Crosstalk avoidance
  • Detection of sound absorbing materials
  • Fully pre-calibrated
  • ROS ready
  • UART / USB dual interface (with USB adapter set)
