Design (and possibly provide prototype) of a circuit to detect low water level and activate a fill valve. Power input is 120v 60Hz AC, output to valve is 24VAC. Circuit would use a sensor that detects continuity between two contacts, using very low voltage/current so that it is intrinsically safe against electrocuting swimmers. Circuit would include an overfill lockout that would disable the fill function for 24 hours if low water level is sensed for more than 20 minutes. Circuit should include LEDs to inform user of functions (power, low water, fill valve, lock-out).

I am in the 6th semester of Electrical Engineering, at a top University of Asia. I have done this project as a semester project. I can do this project better then any one else. feel free to contact.
I have done this project in the past. I can do it for you. Lets talk about the final designs. Bid and time are tentative and will be finalized once I know the final requirements.
I can fully design and provide 1 working prototype for this price. You would need to pay shipping cost. Full design, schematics, PCB layout and working prototype.
