Rutronik System Solutions has developed a board for low power 60GHz radar-based distance measurements and people detection.

The Rutronik RAB3 adapter board can be used to test the use of a fully integrated module as well as the possibility of a discrete development. By accelerating the pre-development phase and reducing costs, the RAB3 helps to bring radar-based applications to market faster.

The board uses the Nisshinbo Smart Sensor Micro-Module for non-contact and highly accurate distance measurements or people counting with the distance, angle, and state detection sensor using 60GHz band millimeter wave.

The Infineon XENSIV 60GHz discrete radar sensor complements the latest radar technology provided with the RAB3. The radar sensor comes with one transmitting and three receiving antennas and the L-shaped antenna can be used for array, horizontal, and vertical angular measurement for advanced radar sensing.

Ultra-compact, ultra-low-power 60GHz radar sensor targets in-cabin applications

IoT control applications have become a trend and with it the demand for sensing devices to collect information. Here radar sensing is highly robust and stable with respect to external conditions such as temperature changes and ambient light.

“Radar detects motion, but does not use the actual images, thus providing a real privacy benefit. With our RAB3, you benefit from a development environment to test compact and lower power radar applications,” notes Stephan Menze, Head of Global Innovation Management at Rutronik.

The Arduino interface means the RAB3 is easy to combine with all other Base Boards and Adapter Boards from Rutronik System Solutions. Combining the RAB3 with the RDK3 Base Board enables detection without privacy issues and operates in badly lit and dark surroundings and localized use via Bluetooth Low Energy. This can be sufficient for some applications such as people detection and presence detection in factories, conference and exhibitions halls, shopping malls or similar.

It is also possible, for example, to connect it to the Text To Speech Adapter Board, which is based on Epson core hardware and software. This second Adapter Board makes it then possible to use the voice output to communicate that a maximum of people are in a room or hall. With the Text To Speech Adapter Board up to twelve languages can be realized as voice output.
