Prism Seat Occupancy Sensor LoRaWAN
Prism is a radar-based sensor designed for presence and seat occupancy detection in railway and indoor environments. It enables reliable, real-time occupancy data without the use of cameras, supporting improved capacity utilization and passenger insights.
Using radar technology with a narrow detection pattern, Prism provides focused and accurate detection within a defined area, minimizing interference from surrounding zones.
With battery-powered operation and low-power communication, it is designed for long-term deployments with minimal maintenance.
Typical use cases
Seat occupancy detection in trains and public transport
Monitoring of office pods and meeting rooms
Indoor presence detection in commercial spaces
Utilization tracking of shared environments
Key advantages
Focused detection with narrow radar lobe (±10°)
Detection range up to 6.8 m
Reliable operation independent of lighting conditions
Privacy-preserving sensing without cameras
Available with single or dual sensor configuration
Battery-powered for flexible installation
Advanced capabilities
Prism uses radar-based sensing to detect presence and occupancy with high precision. The narrow detection lobe enables accurate monitoring of specific seats or areas while reducing false detections.
Variants with one or two internal sensors allow optimization depending on seating layout and coverage requirements.
Rail compliance
Prism is compliant with EN 45545 and EN 50155 for railway applications.
Variants
The product is available in multiple variants with different mounting geometries and sensor configurations.
Installation
Prism is mounted using adhesive, enabling quick and flexible installation on a wide range of surfaces.
