Hi, I am looking for a Raspberry Pi/web server software developer for an existing product. In simple terms, we are looking at using a Pi to measure and control the temperature in a room. The temperature data will be uploaded to a web server via a LAN network connection. The Pi will have an HDMI USB touchscreen to display the temperatures and set operations parameters local via password. The Hardware has been built and is operational, leaving just the coding to complete. The three main sections are shown below. 1. Pi application for temperature control and data transmission. The Pi will also need to request an unlock key from the server for the application to run. (example code available for temperature control) 2. Website coding for Data Collection and Keyserver. This is a simple application to send keys to the Pi from a pre-set table and also collect and store the temperature/operational parameters of the Pi. 3. Website Coding for visualisation server. This code will link to the data collection server and display temperature/operation graphs for sites depending on user access. We have basic operational functional flow charts for the Pi and a few screen designs which can be elaborated on. I can also provide a basic python file to illustrate how the temperature control is intended to work. If you are interested, please contact me and we can discuss in more details. NDA will be required.

I have read your project details. I have to ask a few questions. Can you please message me via chat so we can discuss all the details to elicit all the requirements and hence start the development? I will showcase all the skills and my experience for this project over the chat. Please message me so we can resume this discussion. Can you provide me all the functional/Non-functional requirements via a document? It seems like an interesting project. I would like to discuss all the requirements with you, so I can mark the scope of this project. Please also note that final estimation will be provided once all the requirements will be revealed from your end. Hence, my cost of development & deadline solely depends on what you reveal (in detail). Looking forward to conduct an extensive chat with you.

@fleetways

Thank you for looking at our bid. Sorry for exceeding max budget. If we understand this correctly - below are the 3 distinct components in this architecture: (1)Pi installed with a client for displaying temperature - e.g., Java Fx based client (2)PI client to interface with hardware controller and push data to an external web service (maybe Pi would need light-weight webserver, e.g., Tornado) (3)Regular web application (database, dashboard) to record requests (data) from Pi's Would request your response to help us further the discussion on the requirements. Kindly visit our profile on Freelancer https://freelancer.com/u/fleetways.html - to review our past work - 100+ successful projects, feedback. Looking forward to your response. Thank you.

Hello, my name's Jorge, I am an electronics engineer with experience writing firmware for embedded custom solutions. I have a broad experience using Raspberry Pis, specifically for your project I have experience using the Kivy framework to develop nice GUIs with custom data and effects. I am a good match for your project, as I know I will be able to complete it. I'd like to talk with you about the other parts of the project, involving the screens designs you already have and the complete flow of the system. I don't mind signing a NDA for this project, you can easily set it up using the same Freelancer platform. Please contact me to talk about your complete system, I'd be able to answer any possible questions you may have for me, in order to start working on it as soon as possible. Thanks in advance for your time.

Hello, How are you? I am an electrical engineer, expert in IOT product design and prototyping. I have similar project with yours recently. My project was to measure objects on conveyor using Raspberry Pi and proximity sensor. Data is sent to web server, web page displays the existance of object on conveyor. Your project is same as my prior work but different in using temperature sensor. I am 100% confident to finish your project successfully. Looking forward to having opportunity to discuss on your project in detail. Alexander

@nico2747

Good evening. I present myself to you. My name is Nicolas Moreno. I am an Electrical Engineer with experience in the design of electronic products and systems focused on the application of IOT technology, applying programming, electronic design and the use of networks and communication protocols between devices. I have experience in the development of GUI in python with Kivy, to control the pinout configuration of the Raspberry PI, and the remote communication between Raspberry and BLE with HC-05 using UART protocol. On my profile you can see many projects where I use IOT technology based on electronic design, software programming and Modbus (Master-Slave) protocol. For this project, I will do the following steps: 1) Study and analysis of the basic engineering of the whole system 2) Defines each stage of the system, and how will be interconnected 3) Design the Diagram that express how the system will work 4) Design the electronic circuit to connect the process through sensors with the Raspberry PI 5) Design the screens for the GUI for the control and monitoring of the system 6) Test the system in a small scale (I have a raspberry PI to test it) With the images of projects that I’ve done, I hope to have shown you that you can trust me as an independent engineer, and with that I can be a candidate to work with you on this project. Thanks and regards
