I want to create a multi scaled system using Raspberry Pi’s, so I can measure materials . I want the system to be cheap, whilst being reliable. Each scale will have about a max of 15kg on it, I want it to measure in 5g increments. I’m new to this so I haven’t really got a clue. The components for each scale I would like to fit in a 3D printed enclosure. 1x enclosures with 200x100mm dimensions, and 1x 200mmx200mm enclosures, I want the enclosures to be no thicker than 20mm, assuming the material has a thickness of 3mm. If it works I would like each of the load cells to communicate to a pi Pico which then communicates the weight back to a pi zero which can be viewed on a web-app. I want the Pico’s data to communicate wired e.g. USB other forms, and support a minimum of 6 scales for future expansion. Also I need this to run of a single power output a battery, what would be suitable for that? In attached diagram is what I’m trying to create, dose this work, is their a better approach?
Thank you, help much appreciated.
