Detect water flow (trivial), reduction in weight of
the soap (so you know
some has been used), and (temporary) incresse in weight of the towel (so
you know it's absorbed some water). OK, it doesn't actually prove that
the soap/water were used on the person's _hands_, but...
Tony you're a genius. The TTP (Towel Tester Procedure) is a great
enhancement of our UDP/MS. If the towel is now mounted far enough
away from the sink to avoude that the TU may just wet it directly,
the system will be greatly enhanced.
One more thing, did we already plan for a switch to check if the
toilet has been flushed at all ?
