Create Raspberry 3 automation software and GUI

Hello! Reading your project, I have worked with raspberry and PLC (Relay Logo siemens, PLC siemens S7-1200), I see that there are 3 analog inputs and the HMI screen, let me know if the use of raspberry PI is mandatory, I have all the hardware to develop this project, in my laboratory I have all the elements, if you let me know all the details I could work on your project!

Hello How are you? Thanks for your posting job. I have read your project requirements and I am 100% sure I can complete your project perfectly. ⭐ ⭐ ⭐ ⭐ ⭐ ⭐ ⭐ ⭐ ⭐ ⭐ ⭐ ⭐ ⭐ ⭐ ⭐ ⭐ I have 15 years experience in Circuit & PCB layout design and Microcontroller Firmware design.

I have made similar devices (automated fillers for small production businness, like soap or hot wax fillers and other liquid dispencers) and can do it. In my opinion, RPi is not the best option for this project if you are not planning to use the same RPi for other tasks in the same time. First of all, 7" touchscreen for RPi is not widely available and expencive. When your user interface is static and no other tasks (for example, web-browsing or displaying of big and not static set of the images) is necessary - it is overkill. Using of HDMI display with touchpanel is also enough expencive and will not provide any pros for this particular task. In the same time, there are Nextion displays that are perfectly suits for tis task. In that case, the whole task can be done with Arduino Mega board. It is cheap, widely available and also there are a lot of industrial versions of that controller for a reasonable price (however, with a good power supply any board will work). One of the pros in case of using Nextion: you can use your own graphics (images) and change (refresh) it anytime without changes in the code. However, I can make it with RPi if you have some reasons for it Please feel free to contact me in chat for discussion. I have great experience in creation, modification and remote debug of the code for microcontrollers I have made more than 200 projects on different freelance stocks and have more than 30 years of experience in programming and electronics.

Hello, I have read your project requirements and I propose to realize it. I have large experience with RPi and done some projects for clients here. I have the Rpi 3B and 7"touchscreen so I can simulate and test the project. I'm available to discuss your project. Regards.

Hi I would suggest using an Android tablet with an Ehternet port instead of Raspberry. Just add Ethernet I/O module with relay outputs for the valves and analog inputs for the load cells (via a amplifier). Or as an industrial-grade solution, I would reocommend using a Siemens LOGO with a small Siemens HMI screen. The cost will be a bit higher (not critically, though), but the start time will be very short compared to Raspberry and reliability will be very high. Or as a combination of both - Siemens LOGO PLC (it has relays and analog inputs) = $180 + load cell amplifier 0..10V = $120 + Ethernet 8" Android tablet with Ethernet = $90. Best regards, Denis

Good day, I have deep knowledge in Raspberry Pi designing and development and I can make Raspberry 3 automation and GUI in a quality and timely manner. I have seen the attached png which you mention in description. I would like to have a thorough discussion on this project as there are certain suggestions from my side After dedicating more than 30 years to the electronics design and development, I am passionate in designing the best products Technology wise I have worked on all the latest technologies like GSM, 5G, Lora, Raspberry Pi, GUI etc And have worked on more than 20 design tools for designing and simulation purpose Some of the generic queries from my side are: 1. What is the application of this product? 2. What will be the ambient temperature of this product? 3. What are the mechanical constraints to be taken care of? If you are someone who wants to benefit from my experience just message me Hi and I shall be there for you  Regards Hari Mohan Engineering for one is magic for others

Hello, Do you need help in components selection and programming? CAn I suggest boards which needs to be interconnected using wires, so that you can achieve the final result...... Please share with me the specifications such as target weight range and tolerance. Do you already have one load cell to measure? are they on the conveyor ?

Hello, I'm a software engineer I work with raspberry and hardware integration using python. Will you control the solenoids using a relay I think or do you have an specific solenoid that could be controlled using a signal? Which scale are you using to measure the weight? And how do you read the values from it? Using a serial comm protocol? I can do this in a week and my quote will be higher than your specified budget. Text me if interested. Thanks Martin ------ I invite you to check my profile by clicking on my name, here are some of my clients reviews: - "Great professional. Very fuss free and understands my requirements very well. Will definitely look to work with again!" - "Great communication, delivered super fast solution. Would hire him again, definitely!" Note: Given price on this bid might be a placeholder, final price will be discussed after final details.

Hi, I am embedded system engineer with 8 years of experience, I can help you build automation system with weighing system, valve control, and other IO in raspberry pi or other SBC. please check my profile to see a few of them and if you are interested, we can get started any time

Hi, I have read your project description..send me the solinoid valve specs you want to use.?.. I am an Electrical Electronics Engineer and IOT expert. I have done many projects using Raspberry pi ESP32 and Arduino. Leave a massage for more discussions. Thanks.

Hi, I am interested to help you develop the GUI for RPi for reading the load cells and operating the Solenoid valves. I have good experience developing the GUI application. Please have a look at my profile for my work samples. https://www.freelancer.in/u/prakashanandan89. Expecting your reply.

HI. I have good experience with raspberry pi and can help your project. If u choose me, u will get best result. Regards.

Hello Dear Hiring Manager yes i will make a program for your pi using python which do all the things that you describe above lets have a chat i am ready to start from now

Hi. I am a professional electronic engineer. I have 6+ years experiences with the designing electronic circuit. I also like to use Raspberry pi and arduino board. I read your requirement and saw your img. I can help you with the project. Thank you.

I have understand your project specification and also see your attached image. You want to design a software which will have the ability to read the values of three load cells and operate the solenoid which is linked with the load cells using different types of relays. When user sets a target value the solenoid is actuated and it fills the container till it reaches to the targeted value. All operations will be controlled using 7'' touch screen according to the image you attached. I will do it quite easily. I am an electrical Enginner having 5+ years of experience in the field of Embedded system Micro Controllers, Arduino , Raapebery programming using different softwares such as Kiel for micro controller projects. I have worked on ESp32,Stm32 and 8051 controllers. I also have worked on projects of MATLAB, Simulink , MATLAB coding, PWS ,MUlTISIM and other projects. I have a comprehensive knowledge of Relays such as Allen Bradley Siemens and Schenider. I have also programmed alot of relays and have good handzone experience in DCs and SCADA system also. I will assure you about the quality and timely delivery of your project according to your deadline. Looking forward to work with you.

Hi there Hope you are doing well. I've checked the image and seems the end product will be used in an industrial grade machine . I have the experience in using the Pi as the core-board in similar case such as battery management system, and robotic operation, and can lead this part of your project to a best model. also can suggest you good techniques to reduce the boot loader time and a robust implementation of the system in KIOSK mode. and also can suggest you to use more robust and best alternatives such as ready-made and economic boards such as STM32F429 discovery which has LCD attached as well. I'm interested in your project and like to share my idea with you . BR Vahid

Hi, I hope you are doing well. Im very interested to handle your project. That is clear logic described above. You need to set a weight by 7inch screen to close solenoid valve after reaching target. Solenoid valve is operating like a filler. I have a alot of work to show you related to respberry 3. Just ping me back in chatbox for more details Im looking forward to make a good relationship with you. Thanks Engr Ahmad Ali
