Tasks Completed:

• Tested bright light interferance with Omron Sensors.
  
• Determined that hopefully two omrons will go on both ends of the converyors

Oranges Dave Omron Sensor Data

• No extra shroud around detector during test
• White object detects to 2" (Omron data sheet predicts 1.77", so pretty close)
• Silver Object detects to 2.5"
• Black electrical tape detects to 1"
• Black marker detects to 1" (Omron data sheet predicts 0.78", so pretty close)
• Black paint detects to 1"
• The best distance to tell the difference between white and black is about 1.5" (Omron data sheet would predict about 1.25").  On/off not messed up by green laser pointers. Not messed up by 100watt incandescent light.

Tasks to Complete/Things we want to know:

• Do we want six photoelectric sensors (and if so, consider less expensive ones?)
  
• Want sensors from here?
  
• What sensor to use for shaft encoder on top spinner.

Images & Additional Updates:

(Use the upload file button on the toolbox to the left to upload the file, then insert an image using the button above.  Sizing can be done using the length/width pixel size)
