Electronic Water Sensor Module: Design Circuit/PCB, Code Firmware, Build & Deliver 5 Samples.

$30-250 USD

In Progress
Posted over 2 years ago

$30-250 USD

Paid on delivery
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.
