How do you automatically detect water in Minecraft 1.8?
I'm building an automated farms for several crops, including wheat.
The farm consists of a long cascade of farm fragments:
Seen from side
Currently, I have to manually toggle water off after it reaches the bottom region of the farm.
Is there a way to configure a farm so that the water turns off automatically after the bottom has been reached?
I don't want to use a timer, as I'm looking for a design that is compatible with all tower heights.

I got it almost sorted out :
The daylight sensor is in reversed mode, and the far left comparator is in subtraction mode.
This thing splits the sensor's signal, delays one of them and subtracts the delayed signal from the immediate signal. It is effectively a falling edge detector for daylight. It will periodically output a weak pulse during the afternoon (which is ignored), and a stronger one if light decreases abruptly, which will be the case if you pour water on it. This stronger pulse gets picked up by the repeater and gives you your output.
Limitation : doesn't work around midnight (i.e when the daylight level is 1 or 0).
