Parkki is a Lille smart parking company whose platform uses LiDAR and real-time analytics to report parking occupancy. It added Fleximodo sensors to measure bays from ground level, first with a small batch of surface-mounted units in 2023 and then with a production rollout of flush-mount sensors in 2025.

Why add ground sensors to a LiDAR system?
Overhead LiDAR needs a clear line of sight to each bay. Trees, narrow streets and covered parking can block that view. A sensor in or on the bay measures the vehicle directly through its magnetic signature and radar, so it keeps working where an overhead view does not.
Both sensor types feed occupancy per bay, which Parkki combines with its LiDAR data in one platform.
Why start with surface-mounted Minis?
The Sensor Mini fixes onto the surface, with no drilling or roadworks. That made it quick to place exactly where coverage was missing and easy to move later. It connects over LoRaWAN, so the gateways could sit with existing site equipment. The Mini is rated at 99.7% detection accuracy.
Why flush-mount NB-IoT for the rollout?
For the larger 2025 rollout, Parkki moved to the Sensor Standard, Fleximodo's main in-ground sensor, rated at 99.96% detection accuracy. The flush-mount version sits level with the road surface, so it does not need a full core-drilled installation, yet it is protected against traffic (IP68, IK10).
NB-IoT removed the need for gateways: each sensor reports over the mobile network. That makes it simpler to cover bays spread across several streets or car parks.
