TeraRanger Evo is the long-range Time-of-Flight distance sensor of the TeraRanger product family. It provides calibrated distance readings in millimetres and has a range up to 60m, whilst remaining lightweight and small! Instead of laser, TeraRanger Evo uses LED technology.
One advantage of this is that it enables the sensor to have a “Field of View” so that, rather than measuring distance based on a very small point of light, the sensor measures over an area. At 1m distance the area is approximately 3cm by 3cm. At 10m it is approximately 30cm by 30cm, increasing linearly with range.
For many applications this is a significant advantage and provides a more appropriate and stable datastream. Examples include drone flight over vegetation, a robot navigating close to a slatted fence, or irregular shaped objects being detected at high speed. In addition, the sensor has a unique two-part design.
There is an opto-electronic sensing device (black module, 9g) and a choice of backboard (yellow module, 3g), which simply plugs in to provide communications and to manage different power supplies, without the need for adaptors, converters or complex wiring.
You simply chose the backboard that best suits your application and preferred communications protocol!
USB and I2C/UART backboards are available, but custom backboards can also be made to support specific applications.
Drivers for ROS (Robot Operating System) and popular drone flight controllers are also in development or available, adding to the plug and play convenience.
The sensor is eye-safe and CE certified.
