CO2 Measuring Software for Breath

$250-750 USD

In Progress
Posted over 8 years ago

$250-750 USD

Paid on delivery
I am developing a device that measure the co2 in a persons breath using the device found here. [login to view URL] and [login to view URL] The user will put in the device to their computer through the USB port. I would like it so the user can start and stop a session. During the breathing session the user will see the wave of co2 in their breath similar to the PDF above. It will all be web based. So the data will enter the computer and stream in a chart on the computer and be saved in the database. For each session it will show average peak co2 + average peak co2 + average breaths per minute + average duration of breath (determined by peaks and low points as one breath) + highest peak co2 + lowest peak co2 Each session will be stored date and time with a place to write some notes for each session. Please let me know if you have any questions. Thanks, Steve

Hello :) What you want is possible. I am sorry, but it is very very detailed. You are willing to take the measurement from the sensor and then send it to the computer through USB. After that you want to send it to the web server (that runs either locally or remote) using Web Sockets because your sensor can make up to 20 measurements per second and you want real time monitoring and graphing. That includes 3 layers of technologies hardware, firmware and software, and all of them require good knowledge to accomplish something stable and flawlessly working.

I have read the details of the sensor and their systems. I have 2 questions. 1. Are you going to use the same set of components mentioned in the PDF document? 2. Are you going to use their SDK coupled with a custom program made by me for analysis? I am guessing the answer is Yes to both the above questions. I am an expert in C# .NET desktop applications. I am an electrical engineer and have extensive experience with working on desktop applications that interface with hardware. I have worked with Agilent 34980A Data Acquisition System hardware, Schneider PLC systems, Sepam relays, etc. at my work and have developed programs that are used for day-to-day activities. I am confident I can build a program that will suit your requirements and exceed your expectations. Please feel free to contact me for any further details about implementation of the program. Looking forward to working with you, Best Regards, Ananth.
