Automatic Nutrient Feeding System for Hyrdoponics

Paid on delivery
I would like a automated system that measures the pH, temperature, and electrical conductivity of water. When these measured points are out of the desired set points, I would like the system to then correct the problem by adding 1 of 3 different solutions to the stock tank to bring the levels back into the correct settings. As for temperature, I would like the system to turn on a water heater if the stock tank is to cold, or a water chiller if the system is to hot. I know these are separate systems, but would like to have the ability for a complete system. This will be using things like peristaltic or solenoid pumps to make the changes needed. I'm looking for a cost effective solution, because most systems currently like this are typically $2500+. The other thing I'm looking for is for this system to have either wired or wireless internet capability. I would like to be able to access the system's data through either a computer or smart phone, but don't need you to develop the software for that, I just want you to develop the mechanical side of the equation. As long as a computer could access the data points collected by this system, that's the important part. I'm willing to discuss this more at length with people who are interested.

Hi, I can do this project for designing the automated system, but as you mentioned at the end I agree to you that it require a great level of discussions to calrify the requirements. From logical point of view following shall be the milestones: 1. Specification requirement document. 2. Schematics using Altium 3. Simulation of code and electronics (Where ever possible) 4. Software delivery. But my this BID is for Part 01 i.e specification requirement document ; or you can say its a feasibility and once it's done then rest of the things should be considered. Specification requirement shall cover the following: 1. You all requirements in detail 2. Feasibility of each individual requirement 3. How each requirement can be full-filled 4. Keeping the money constraint as you mentioned. 5. System block level diagram. About my self , I have 14 year experience in electronics, micro-controllers and system designing, i am quite confident that I can take your project. You can also review my profile and my clients comments. Best Regards.

hello i am electronics engineer, i have long experience in prototyping work, adding sensors like PH, temp and conductivity, is so easy the algorithm gonna be as this, firstly we need to certify the controller how will collect the data from the sensors in the water tank, then we compere this reading with reference reading which is saved inside the microcontroller, then the desgin will have ability to control the pumps,heater...etc we might recommend some new ideas about your project during the conservation, we have a long team, team which able to work with you and travel at you to solve any prototyping problem, we take a consider at the price its will be low according to prototyping works, we can make a deal with you, and we have stander platform for android application and web service, so hopefully to send us either here or by email

Great references and overview of the project. I've read them. But what you are asking for here is really quite complex. It takes researched experience to create an effective system; practical, cheap, low power, meets customer needs, etc. I'm sure competitive systems have a great deal of developed knowledge you cannot get from the web. You will have to rediscover the important parts. You want a technical business partner in this for the long term. Your customers will need after-sale support so you need someone who can analyze situations and provide ready answers for specific issues that arise. Otherwise, you lose customers and reputation. If a consultant, someone in the US and someone with a long track record of supporting clients. Business partner would be better. I've been a consultant since 1985 and supported products with decades of market experience. I can refer to them to ask about their experiences with me. Also, feel free to write me and talk anytime. I enjoy helping others think about such things, even if I'm not engaged in the project. I may be able to offer a thought or two. My bid is mostly so I could say the above to you. The project IS interesting. It will involve some intriguing closed loop control as well as significant design work. But I don't think this freelancer thing is the right format for a successful partnership. I think we'd need to talk quite a bit more before I'd know enough and before you'd have confidence in my skills.
