There is one very simple way to do this and it is to make a stand alone system that simply manipulates to outputs of opensprinkler. This would then not require any changes to any opensprinkle and would be connected in series with each output. When the desired soil moisture was reached, it would simply cut off that channel until the humidity dropped. This method has the advantage that there is no hardware or software needed. The moisture threshold would be set by potentiometers on each channel The down side is, of course that moisture sensor management would be entirely manual which is not that great.
I think that it would be best to integrate it with opensprinkler. It would be nice and helpful to have access to the moisture levels in the interval program. Then we could easily monitor the humidity and make adjustments to the variables based on how our plants react to different levels of humidity.
