That's not good!!!! I have to somehow, measure the ambient lighting every minute or so and then, based on the required distance, I have to set the correct current for the IR led so there would be no IR overshoot in respect to the amount of ambient lighting at that instance in time.
The neighbor kid had one of those helicopters which used IR. Every time he took it outside it would crash and act crazy. He thought it was broken.
You may have to use a different method for determining distance under these conditions.

You have a micro at your disposal so you could probably have another sensor that just detects ambient light. It may still be a tricky calibration by trial and error.

yes, I thought about that.... but before I go down that route
I am waiting for the tssp4038 to come in as this is a fixed
gain part as suggested a few posts back in this thread. Vishay
also suggested this part for this application.... as marked on the
spec, this is one of their new parts.
