Richard,

Thanks for the suggestion. I've been having some issues and have to agree that these sensors are not really suitable where precision is required. I added tabsofts suggestion, and I got as many short errors as I did Longs... I've also got several not connected errors. I think I'll look at something that uses a standard communications interface such as those suggested by Tim.

The humidity requirements of the snakes I keep are not that critical, but this probe is intended to be used to monitor the humidity in the container containing eggs in an incubator, where the humidity needs to be kept at a set range so they don't dry out.
