VL53L4cd not able to detect dark surface

[pthakkar]

I am trying to use VL53L4CD to detect whether there is a car on top of the sensor or not...I am placing my sensor on the ground and trying to detect if a car is parked on top of the sensor. But it is not able to detect the cars bottom surface. However if I place any other object it is able to detect that....

Is this the right sensor for this application?

For detecting a car usually inductive sensors are used, something like a big wire loop in the ground.

Optical sensor on the ground is a bad idea, just imagine some drops of black oil dropping down...

Oil spillage and things have been taken care of. Only issue is that the sensor is not able to detect the car when it is on top..

Hello. No, it is not possible for an L4 not being able to detect a target
at ~40 cm.
