I ran across this unique mist controller:

Has anyone had any experience with this method of controlling misters?

The hort department greenhouse at the community college of the county I live
in has one installed on their misting bench. The instructor seemed quite
taken with it. I think it is meant for a localized heavy misting area, like
for rotting cuttings.

LOL. Was that Freudian, or intentional?

Any use in an orchid greenhouse should be careful to
avoid constant wetting and rewetting of the plant's leaves.

I can see the "leaf switch" used a safety device to override scheduled
(via timer or humidistat) misting when the previous misting hasn't yet
evaporated.

On the cutting
bench its use was accompanied by a lot of preventative fungicide and
bactericide applications.

I get it; reliance on the "leaf switch" alone will likely lead to over
damp conditions.

Get the catalog from Dripworks. It has lots of misting equipment, timers,
values, etc...

Many thanks for the link. I'll check it out.

You seem pretty familiar with controls. You wouldn't be aware of any
water sensors for use in controlling irrigation would you?

Thank you for your informative follow up.
