There is no minimum weight a car needs to activate the sensor. ParkHere sensors can also capture bikes and motorcycles; and they are so sensible that 100% functionality is guaranteed even under snow surface.
The smart software behind the sensor is capable of defining patterns for different elements in order to identify them when crossing over the sensor. These patterns are conditioned by weight, number of wheels, etc., making it possible to identify when a car, truck, pedestrian or bicycle crosses over.
In this way, the parking facility managers can decide what he or she wants to capture precisely. The software can ignore the sensor-activations caused by passing pedestrians, bikes and other non-desired sources.
