We are looking for someone to finish designing a schematic and PCB in KiCad. The circuit is a secondary module for a hydroponics controller. The PCB uses two sensors from Atlas Scientific: a pH and an EC circuit. It also has an HC-SR04 sonar sensor. Everything connects to the main board through an RJ45 cable. Communication is made to these sensors through serial. The critical problem we have is that Atlas Scientific's circuits are very sensible to noise and ground loops so proper isolation is needed. We have an untested circuit that needs some skilled engineer to see if it will work correctly without issues. The project is open-source and will be licensed under CC 4.0 BY-SA. The main board's files are located at: [login to view URL] The work in progress for the module that is in need of a retouch is here: [login to view URL] The two circuits that will be used along the module are these: [login to view URL] and [login to view URL] Through-hole components will be preferred and ideally two versions, smd and through-hole, will have to be made. Part's list should be included. An explanation of the circuit will be a plus. If possible, we would like to add a DS18B20 temperature sensor to the board but we are not sure this is possible, as all RJ45 cables are already used for communication.

Hi, Thanks for sending an invitation for Placing a bid. I am Electronics Engineer having R&D experience of 10+ years. I have developed number of signal conditioning circuits having such problems. We can apply filters and Noise problems can be eliminated. Since the project is under dvelopment, i would suggest to simulate the circuit in begning and then try a prototype. For this purpose the circuit should be tested in proteus,Electronic workbench or Labview. Once the things are simulated and have satisfactory results we can go for PCB design. Again since the circuit is sensitive we should implement the PCB on multi layers. For more information please feel free to contact. Have a great day. Best Regards, Shahbaz. Addition: Sorry i forgot to mention, The noise reduction can be done thru various techniques like using high impedance instrumentation amplifiers, isolating data and power lines and also thru ADC sampling.

Dear Sir or Madam, I was pleased to run across your hydroponics project. I am an Electrical Engineer currently living in Medellín, Colombia (South America). I am an avid hydroponics fan and have designed my own personal hydro systems. I feel that I can contribute some extremely useful advice to your project. I am happy to let you know that I recently completed a hydroponics timing circuit for a current client. He was very satisfied with the product. I understand your problems with noise. In my previous position as lead Electrical Engineer at my previous company, I designed circuits that were meant to measure pA and fA level currents that were very very very susceptible to noise. I am absolutely confident that I will be able to help you with your noise vulnerabilities. I will also do my best to add your DS18B20 temperature sensor to the design. Additionally, I am bilingual if you prefer to communicate in Spanish. I have tried to bid on this project thinking about our timezone difference and any questions I may have. I look forward to working with you! If you have any questions, please feel free to ask. Best Regards, Jameson Beebe
