I am a school teacher. As part of the code club(10 -12 yr olds)I run we want to set up an irrigation system for our school green house. Our project would be adding a rain sensor and modifying the code.
Can anyone help with what we will need in terms of water valves, hoses etc. We will get the opensprinkler and whatever hardware is needed for opensprinkler but I am lost with what we would need in terms of the water valves etc.
In terms of what we have at the moment it is a garden hose and taps.
Any help you guys can give would be greatly appreciated.
