Radar sensors for IoT
XENSIV™ 24 GHz and 60 GHz radar sensing solutions for industrial and consumer applications
As market leader in radar chips, we offer a wide portfolio of mmWave radar sensors as part of our XENSIV™ sensor family – including Doppler radar as well as FMCW radar systems. This portfolio includes the smallest 24 GHz MMIC in the market as well as the largest and most integrated 24 GHz radar transceiver family currently available. Those radar chips are designed to support different industrial, home and consumer applications. In addition, we also have radar sensors in the 60 GHz range, which are used in consumer products such as the Google Pixel 4 smartphone.
Motion detection with radar sensors offers significant advantages over PIR and other motion sensing technologies
With our 24 and 60 GHz radar sensors we cover a wide range of applications. Many of them are based on motion detection triggering systems like lighting solutions, automatic doors, camera and security systems or smart home devices. In contrast to other motion detection technologies like PIR, radar technology offers significant advantages. These include smaller system sizes, greater accuracy and more precise measurements of detected objects. In addition, radar can also determine the direction of a moving object, speed of an object, distance and, depending on the antenna configuration, even the position of a moving object.
When to use 24GHz or 60GHz radar technology
In the 24 GHz range the bandwidth for FMCW radar operations covers 250 MHz within the regulated ISM band. In the 60 GHz regime, an unlicensed ultra-wideband of up to 7 GHz can be used for short-range applications. Consequently, 60 GHz FMCW radar systems can offer a better resolution and therefore allow additional use cases such as human tracking and segmentation. Even gesture control, material classification or the monitoring of various vital functions (respiration, heartbeat or even blood pressure) is possible with radar technology due to micro motion detection.
