Precise motion detection for reliable building automation

Motion and presence detectors are key components of modern building automation. They ensure that rooms are only lit, air-conditioned or ventilated when there is an actual need. In modern building structures, however, classic PIR motion detectors are increasingly reaching their technical limits. Many unwanted switching operations are not caused by installation errors, but by the inherent limitations of PIR technology. PIR sensors respond exclusively to heat radiation and do not provide any information about position, distance or direction of movement. As a result, movements in adjacent rooms, corridors or behind open doors are often also detected.

Product features: 60 GHz presence sensor technology for error-free motion detection

• Position-based motion detection with distance and angle
• Clearly definable, zone-based detection areas
• Reliable detection of relevant movements – no peripheral or secondary movements
• High sensitivity for presence applications with short follow-up times
• Compact design without optical elements such as Fresnel lenses
• Data protection compliant: no image or personal data

Reliable motion detection for dependable operation

60 GHz radar sensors detect real movements in space and determine both the distance and angle of a person. On this basis, detection areas can be configured as clearly defined zones. Movements outside these zones are reliably ignored – even if they are within the maximum range of the sensor.

Radar-based presence detectors only detect abstract movement and position data. No images or personal information are processed. Combined with modern signal evaluation, this results in a reliable, precise and design-friendly solution for demanding smart building applications.
