Electronic Water Sensor Module: Design Circuit/PCB, Code Firmware, Build & Deliver 5 Samples.
Budget: $30 – $250 USD
Module Function:
Water touching two electrodes (connected by 2 wires (+,-) to the Module PCB) causes 36VDC to be sent to 2 Output wires (+,-). A current sensor alarm circuit sends 0 or 5VDC to 2 Alarm wires (+,-) if Output circuit amperage is Low or Normal.
a) Power Source: 36VDC.
b) Controlled Output Circuit: 36VDC 3A.
c) If Amperage of Output circuit >0.5A, 5VDC is sent to Alarm wires. If circuit current <0.5A no voltage is sent to the Alarm wires.
1) Your bid to include: Circuit design, PCB design, firmware code, parts/assembly, and courier fee.
2) Deliverables: All files needed to manufacture Module. 5 module samples. Built, tested, and delivered to the USA.
The uploaded file is a sample electrode sensor circuit that I have successfully employed in other designs. It can be used as a starting point for the circuit design of the Module.
