Smart Seat Occupancy and Seat Belt Monitoring System
Real-Time Seat Detection for Smarter Passenger Transport
Monitor passenger seat occupancy and seat-belt status through an integrated, sensor-based monitoring system designed for buses, coaches, school transport and commercial passenger vehicles.
Linepro’s solution combines pressure-based seat occupancy detection, seat-belt buckle sensing, wireless communication and a central display to provide drivers with real-time information about individual passenger seats.
Key highlights:
- Real-time occupied and vacant seat monitoring
- Seat-belt fastened and unfastened status
- Monitoring for up to 40 passenger seats
- Wireless communication between seat nodes and the master controller
- Compatible with 12V and 24V vehicle power systems
A Smarter Way to Monitor Passenger Seats
Knowing whether a passenger is seated is useful. Knowing whether an occupied seat’s seat belt is fastened provides additional information for passenger monitoring.
Linepro’s Smart Seat Occupancy and Seat Belt Monitoring System is designed to detect passenger presence at individual seats and monitor the corresponding seat-belt buckle status. The collected information is transmitted to a central controller and presented on a driver-facing mobile phone display.
The system uses pressure-sensing technology for occupancy detection and a separate seat-belt sensor to monitor buckle status. Wireless communication between distributed seat nodes and the master controller helps reduce wiring complexity within the vehicle.
Designed for passenger transport applications, the system supports real-time monitoring, centralized seat visibility and integration planning for vehicle manufacturers and transportation system integrators.



From Seat-Level Sensing to Driver Visibility
Each monitored seat has occupancy and seat-belt sensing inputs connected to a seat node. The node monitors the sensor information and communicates wirelessly with the master controller.
The master controller collects the information from the seat nodes and updates the driver’s display. This allows the driver to identify individual seat conditions through a centralized interface instead of relying solely on manual seat checks.
The system architecture is designed to support monitoring of up to 40 passenger seats.

Designed for OEM Integration
A Flexible Platform for Bus Manufacturers and System Integrators
Every passenger vehicle has its own seating layout, electrical architecture and monitoring requirements. A seat occupancy monitoring system should therefore be evaluated according to the intended vehicle configuration.
Linepro’s Smart Seat Occupancy and Seat Belt Monitoring System provides a modular architecture built around seat-level sensing, wireless seat nodes, a master controller and a driver-facing display.
The solution can be evaluated for integration into new vehicle platforms or suitable existing vehicles, subject to installation and compatibility assessment.
Potential integration considerations:
- Seat structure and sensor placement
- Number of passenger seats to be monitored
- Seat-belt buckle sensor compatibility
- Vehicle power supply and electrical protection
- Wireless communication conditions inside the vehicle
- Driver display layout and warning requirements
- Interfaces with external fleet or vehicle monitoring systems
Frequently Asked Questions
What is a smart seat occupancy and seat-belt monitoring system?
It is an electronic system that detects whether individual passenger seats are occupied and monitors the corresponding seat-belt buckle status. A central controller collects the information and presents it on a driver-facing display.
How does the system detect seat occupancy?
The system uses pressure-sensing technology to determine whether a passenger is sitting on a seat. The sensor information is monitored by the seat node and communicated to the master controller.
Can the system monitor seat-belt usage?
Yes. A separate seat-belt buckle sensor monitors whether the belt is fastened or unfastened.
How many seats can the system monitor?
The datasheet specifies support for up to 40 passenger seats. Confirm the required configuration with Linepro for your vehicle application.
How is seat information displayed to the driver?
A simple mobile phone display provides a real-time seat map, occupancy monitoring, seat-belt monitoring, seat identification and warning indications.
Does the system require wired communication between every seat and the central controller?
The documented architecture uses wireless communication between distributed seat nodes and the master controller, helping reduce communication wiring complexity. Power and sensor wiring requirements depend on the installation.
Which vehicle power supplies are supported?
The system is designed for 12V and 24V vehicle supply systems.
Can the system be integrated into existing buses?
Integration may be possible following an assessment of seat construction, electrical compatibility, sensor placement, installation conditions and display requirements.
Can the system be customized for an OEM project?
Contact Linepro to discuss the required seat configuration, monitoring functions, vehicle electrical system and integration requirements.
