Hi Ray, guys,
I have a proposal for the next generation Open Sprinkler as follow:
WSMU – Water Supply Management Unit – a part of the hardware/software which cares about the water supply, either from a tank, or well or main water supply. The weak point of all irrigation/sprinkler units on the market is that almost none of them takes care/management of the water supply. The presumption is that you have always water at hand, but it is not always so easy. In some regions, you have to either source water from a well, or fill a water tank. This makes the task a bit complicated because you’ll need another controller to take care of.
I attached an example of my irrigation system which uses Zelio Logic SR3B261BD to take care of everything, including water sourcing. You may freely use it as a reference.
The language is FBD with full description which you can easily read and implement into the Next Gen OS.
