Provide Gerber, BOM and CPL files for Water Detection Circuit
Budget: $30 – $250 USD
I require a circuit that detects the presence of water when 2 probe wires are submerged.
The dimensions of the circuit board should be 54.5mm x 21.5mm
The circuit should operate at both 9v and 12v
The LED should only illuminate when the resistance between 2 probe wires falls below 10kOhm
The power, LED and probe wires will be connected by XH 2.54 connectors:
Power is to be supplied by an XH2.54 connector with the polarity in the image provided
The LED is to be connected by an XH2.54 connector (polarity independent)
The probe wires are to be connected by an xh2.54 connector
The surface mounted XH2.54 connectors should be orientated vertically (as pictured) so that the surface of the board can be coated in resin to waterproof it.
