Rutronik Adapter Board – RAB3 for Radar

Testing distance measurement and people detection in one

Reliable solutions for distance measurement as well as people and surface detection play a key role in IoT applications. For such applications, there is a strong demand for smaller and lower power radars. With the RAB3, the experts from Rutronik System Solutions are expanding their board family with an Adapter Board to test the use of a fully integrated module as well as the possibility of a discrete development. Your advantages at a glance: Benefit from a shorter pre-development phase, reduced costs, and an overall shorter time-to-market. Another advantage is that all Adapter Boards and therefore also the RAB3 can be easily combined with another via an Arduino interface. Take advantage of this unique development environment from Rutronik System Solutions to realize your application.

The advantages of Radar over camera and infrared technologies

IoT control applications have become a trend and with it the demand for sensing devices to collect information. There are also other technologies such as cameras and infrared being used for such applications, but Radar has some real advantages here. Applications that rely on cameras to detect people and their movements raise privacy concerns because they record images. Radar instead detects motion, but does not use the actual images, thus providing a real privacy benefit. Radar has another advantage over camera technology because it also works in the dark to detect movement. Radar sensing is highly robust and stable with respect to external conditions such as temperature changes and ambient light. This is an advantage of Radar compared to infrared sensors. 

Target markets & applications for Radar:

  • Presence detection
  • People counting
  • Distance measurement

Advantages of Radar:

  • Preventing privacy concerns
  • Robust and stable technology (e.g. temperature changes, ambient noise)
  • Realizing detection also in poorly lit and dark environments

RAB3 combines state-of-the-art components for Radar

The Adapter Board RAB3 from Rutronik System Solutions uses only state-of-the-art components from the Rutronik portfolio. One centerpiece is the Nisshinbo 60GHz Smart Sensor Micro-Module. Radar sensing at 60 GHz is a non-contact and highly accurate measurement solution. Realize your application in distance measurement or people counting with the distance, angle, and state detection sensor using 60GHz band millimeter wave. Another advantage of radar sensors is that they can also be installed behind certain materials. They are concealed behind surfaces such as tiled or plastered walls, making them invisible and facilitating cleaning work on surfaces. This is particularly advantageous for environments with high hygiene requirements, such as hospitals and care facilities.

With the Infineon XENSIV™ 60GHz Radar Sensor, a discrete radar IC complements the latest radar technology provided with the RAB3 to work on your application. Thanks to its small form factor and low power consumption, this 60GHz radar sensor comes with one transmitting and three receiving antennas. You can realize array, horizontal, and vertical angular measurement based on the the L-shaped antenna. This enables advanced radar sensing.

Benefit from developing applications for distance measurement and people detection with the use of our Rutronik System Solutions smartphone app with firmware examples. This allows you to just use one board to test the possibility of a discrete development or the use of a fully integrated module.

One development environment countless use cases

Thanks to the Arduino interface, the Adapter Board can be easily to combine with other Base and Adapter Boards from Rutronik System Solutions. The modular concept enables a variety of approaches to implement your development project quickly, inexpensively, and simply, yet in a technically sophisticated way. 

By combining the RAB3 with the Base Board RDK3, it is possible to implement both detection without privacy issues and also in badly lit and dark surroundings and localized use via Bluetooth® Low Energy, which is 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. Benefit from up to twelve languages that can be realized as voice output with the Text To Speech Adapter Board.

Advantages of the RAB3:

  • Hardware for the development of proof-of-concepts
  • No need to develop your own hardware for first evaluations
  • Reduces costs, accelerates the pre-development phase, and applications reach market maturity faster
  • Quick and easy testing of the possibility of a discrete development or the use of a fully integrated module
  • Easy to combine, for example with the RDK3 from Rutronik System Solutions, thanks to the Arduino interface
  • All components can be found in the Rutronik portfolio
