TeraRanger benefits

Small and lightweight

TeraRanger sensors are the smallest size and lightest weight ToF distance sensors on the market at this performance level. (A TeraRanger One weighs just 8g!) This means that sensors can be placed in locations not previously possible when using larger, heavier sensors. For mobile robotics, including drones, this is a real advantage!

Long range


Despite their small size and light weight, TeraRanger sensors pack a powerful performance punch! TeraRanger One can measure distances at up to 14m range. And this is done with LED technology, not a laser! (See section on LED illumination.)

Fast refresh rates


TeraRanger sensors are optimised for high-speed readings. TeraRanger One can measure distances at up to 1000 readings per second! In addition to being small and lightweight, high data refresh rates are central to our design ethos, making the sensors ideal for fast-moving applications, from mobile robotics to industrial automation and smart city applications like traffic monitoring and management.


LED Illumination


Instead of using laser emitters we use Infrared LED technology. This brings a number of important benefits.

Eye-safety: TeraRanger sensors remain eye-safe in all conditions, with no need for Laser Class 1 safety precautions!

Field-of-View: Rather than measuring a very small point, we can allow the emitted light to spread and form a Field-of-View. In many applications, this can be a distinct advantage. Imagine a sensor trying to detect a tree. With a laser, you might detect the leaves, or pass through the gaps and detect something much further away. In a robotics safety or anti-collision situation, this could spell disaster. With TeraRanger technology you are far more likely to detect the hazard you want to avoid. Generally, at 1m to the target, a TeraRanger One sensor is measuring an area approximately 4cm by 4cm.

Power consumption: Compared to some laser devices, LED’s consume far less power; something all users relying on battery-power will enjoy.

Easy to use


All TeraRanger sensors are plug and play. There is no customer calibration to do and no need to convert complex outputs into distance readings. TeraRanger sensors simply stream calibrated distance values in mm’s. We take care to compensate for environment variables, such as temperature and ambient light, automatically and instantly adapting to the conditions to provide the highest possible performance.

The sensors support multiple communication protocols and in most cases, when you connect the sensor, it will automatically recognize the host computers communications protocol (typically Serial/UART or TWI/I2C) and load the corresponding firmware.


Plug and Play support for multi-sensor, multi-axis use


Only TeraRanger technology provides a simple plug-and-play approach to multi-sensor applications. TeraRanger Multiflex for example provides 8 sensors connected to one flexible bus whilst the TeraRanger Hub allows up to 8 TeraRanger One sensors to be connected, with the Hub centralizing power management, sensor synchronization and communications. Sensors can be placed in almost any direction, providing a fast and efficient way for clients to create custom arrays and configurations.
