Radar presence detection

Powered by XENSIV™ 60 GHz radar

Imagine a smart home where your devices can sense you and act accordingly. Think about speakers that always know what room you’re in, lights that automatically turn on when you enter a room and turn off again when you leave. Devices that activate as you approach.

Infineon’s highly accurate radar-based presence detection solution enables all of this – and more! It allows smart devices to detect whether someone is in the field of view and to intuitively interact with that person.

How radar can make your home intuitively smart

Infineon’s radar presence detection solution

Infineon’s radar presence detection solution enables the detection of human presence within a configured distance. Enabled by our XENSIVTM 60 GHz radar with its sophisticated radar presence detection algorithm, this solution provides extremely high accuracy in detecting both micro and macro movements.

The radar range can be individually configured – to detect human presence at a distance of up to 5 meters. Gone are the days when you had to wave frantically to turn lights on or move about to keep them on.

How it works?

At Infineon, we believe technology that learns from you and adapts accordingly to your choices enriches your life. With the help of Infineon’s sophisticated radar presence detection algorithm we are continuously developing new applications to make your life simpler and richer.

The XENSIVTM 60 GHz radar continuously tracks targets within an angular range up to a configured distance. The figure below illustrates the functionality of radar when the target is detected in the configured range.

Yes, the detection range for human presence can be configured from 20 cm to 5 m.

Yes, Infineon’s solution can be used outdoors. However, a wider range might be required for some outdoor applications. If you need a wider range, check out Infineon’s 24 GHz industrial radar solutions.

Reliable presence detection is possible within a 5-meter range.

Infineon’s radar presence detection solution is very sensitive, offering unique benefits over conventional technologies deployed to detect human presence. This presented technology reacts to human breathing (even if people are not moving). The ability to detect these micro movements makes it perfect for intuitive user interaction with devices. It means that users no longer have to wave in front of sensors to make sure that lights stay on (or similar).
