Re: Water level / Detection pcb

Hi Neil

> I did something like this about ten years ago

What!!! and theres me thinking im on a winner ;-))
I actually board a nice little controller which had an addon board for the
water level monitoring from an Oz company here in Seaford called
Splat....This was going to control my Water Harvester pump and valves
etc....but i changed my mind and decided to use an old Telemecanique tx17
plc which i have a handheld programmer....so my waterboard relay outputs
will connect to the plc inputs....
