We need a simple PCB designing and making that can open and close 2 230V solenoid valves (via relays) and that can read water pressure via a transducer and can measure water flow rate. We have datasheets for the two transducers - the pressure transducer works on voltage and the flow via frequency. They are RS components 446-8309 and 797-5037. There should also be a large LED display (or bright LCD) for pressure and flow display and for overall success or fail.
Software should be written that goes through a sequence of opening and closing the solenoid valves and checking pressures and flows are within bounds. The sequence is very simple, the principle difficulty will be reading transducers and displying valves. The should be a push button to start the process.
We would prefer a standard hardware set up like arduino or blackberry that we can replace maintain. Please note we DO NEED ANY BESPOKE HARDWARE. We can buy parts and ship to you and will pay for components needed.
