Counting objects that enter an exit with SEN0305 HuskyLens AI Machine Vision Sensor

Huskylens can only recognise learned models.
In car park scenarios, where vehicle shapes may vary greatly. huskyLens is less effective at recognising them.
Could you consider using two ultrasonic sensors as vehicle counters?

For example, if ultrasonic A triggers first and ultrasonic B triggers later, it means the vehicle is entering. The opposite would indicate a vehicle pulling out.
