PhotoSensor Mounting

Hi, my team is having trouble mounting the photo sensors and we have a question do you mount them looking straight ahead or looking at the floor.
Thank You

You will need to mount them looking at the floor. Our team made a simple plate out of Polycarbonate to mount them.

Simply drill 3/4 inch holes to fasten the photo-sensor, and you are good to go!

Thank You very much:]

Are we mounting them horizantally or vertically?
