TeraRanger One Type A


TeraRanger One is a lightweight, high-performance distance measurement sensor based on infrared time-of-flight (ToF) technology. Type A is best suited for indoor use.



Add To Cart


The TeraRanger One's performance and lightweight design enables robotics applications that were previously impossible with slower sonar sensors or big heavy lasers. The sensor is fully eye-safe, pre-calibrated and ROS compatible. Simply attach it to your robot and you’re ready to go!  Its cost-effectiveness makes it suitable for high volume usage as well as powerful research and DIY applications.

TeraRanger's USB and I2C adapter cables allow direct connection between TeraRanger sensors, host computers, I2C ports and hubs.  They provide the correct voltage level translation and power to the sensors.  I2C adapters enable direct connection to drone flight controllers as well (including Pixhawk).  Though many of the sensor's features are plug and play, if you need to flash the firmware, please contact TeraRanger support to request it. You will then need their USB cable in order perform this operation.
