I'm a novice with an idea, I need a simple analogue circuit to sense moisture triggering a piezo alarm and vibrating motor. I need a circuit and components. Initially 4 components, $40. The final goal would be "think lilly pad" sending data to an app. If we can work together to design and manufacture, then a reasonable stake in the results can be negotiated. I studied as an electronic engineer 35 years ago, but never made it, I now need a young enthusiastic brain to help.

HI there, I like your idea of using analog circuit to sense humidity. I have done it with digital sensors, and doing it in analog is a new challange to me as well. If you are willing I can work along with you to achieve your final goal of the extended project as well. I am good at both communication and innovation and I think I am the best candidate for your job. I graduated on 2016 year and have close to two years of experience in complex to simple circuit design. Let me know if you are interested, we can start work immediately after clarifying a few things. Best regards.

Hello, I am interested to work with your schematic. Easiest approach would be just to stick two probes in material you want to check (soil?) and depending how wet it is there will be more or less of small conductivity. Then it is possible to build analog circuit around this to activate piezo beeper and / or small vibrating motor on some threshold. Some calibration will be necessary to get it right. But it gets a bit more complicated as to avoid corroding probes it is best not to apply voltage all the time, but check it on some intervals. Let me know if you are interested.

Summary: Always tinkering with the idea of building something new and innovative captures my attention. Going towards the unknown platforms and moulding ideas into products is what defines me basically. On the academic level, currently a Post-Graduate student in Electronic Systems Engineering. On the professional front, for more than 1 year, worked as Hardware and Embedded Engineer in TekUncorked for designing IOT modules and Power Management for the same. Proposal: Components Cost: As you described -> 40$ Day 1: Describing the Problem-Statement in detail and finalizing the Specifications for the same.     Literature Survey for the datasheets and Rough architecture (Arch. 1.0) (In between 1-2 days for the components sourcing and ordering. Take the worst case 3 days)     Within this period, Arch. 2.0 for the circuit and finalizing it in theory. Day 4-10(1 week): Working on the design and testing each block of the circuit. Day 11: Demo and Test Cases and Scenarios. Final Testing. Day 12: Submitting all the Schematic, Datasheets, BOM. Note: 1.     1 week time can be reduced based on the how fast it integrates and based on the complexity of the circuit. 2.     On the final day, presenting what I have built and and preparing the Day 12 files. 3.     Bid Price is excluding the components if the circuit components have to be couriered .
