A decision is to be made as to whether optical proximity sensors can be used for car
washes to control movement of the drying nozzle as shown in the illustration below.
After the car has been washed, a gantry bearing the drying nozzle which extends
across the width of the car, traces the contours of the car. The task of the proximity
sensors is to ensure that the drying nozzle constantly follows the contour of the car
at a certain distance. The proximity sensors may be splashed by water during the
preceding wash cycle.
Which type of proximi...
