* Mike said that sensitivity should be secondary to ruggedness and cost because the sensitivity that we are looking for is not high and most sensors will meet our needs. Thus, our approach should be to find sensors that we think will work and then send him the specs for him to OK.

Mike says that we could build a turbidity sensor using LEDs and fiber-optic cables without too much difficulty. He is willing to help with construction if necessary.
