  • I’ve done a couple of simple tests with a 4mm square balsa wood stick at ~30cm from the sensor. I shall refer to the data sheet for orientation description - so that the emitter is to the left or right of the detector (as opposed to above or below). When the stick was oriented vertically, and passed from one side to the other, it seemed to have a 2.5 degree detection beam. When the stick was also oriented horizontally, and passed from below to above (or vice-versa), it appeared to have a 3.0 degree detection beam. I hope this helps.

  • I don’t, but I’ve used the second plot from the data sheet (output voltage vs inverse of distance), called it a straight line from 30cm to 150cm, and a different straight line from 20cm to 30cm. Then it is easy enough to come up with two equations calculating distance from voltage.

No public wish lists :(
