The goal is to build an application on a Raspberry Pi that listens for data (basically a number) from a pressure sensor on a plugged in USB interface and displays the data on screen. The data should be presented as numeric and as QR-Code (or as 'waiting for data'). Specs for the USB pressure sensor: [login to view URL] When starting the Raspberry Pi the application should start without user input.

I'm an experienced developer with a keen interest in the Raspberry Pi. I've worked on many Pi related projects using various input/output boards. I have previously read USB RS485 load cells which are similar to your pressure sensor. There is a Python library available to generate the QR code. I would probably use the PyGame library to display the number and QR code. I would be very interested in working with you on your read sensor data and display project.

Good time! I have an experience with electronics design, sensors communication, data collection. Also I am a SCADA - PLC specialist and Python programmer. I think I can help with Your project. For successful I will need to connect remotely to Your Raspberry Pi with sensor attached for testing protocols API. You do already have USB pressure sensor, is not it? If You hair me I can offer various ways (mqtt etc...) of transferring data to the top-level system and upgrade the program if agreed.
