Particulate matter pollution monitoring system (:poland: System Pomiaru Stężenia Pyłu w powietrzu)
This repository contains my bachelor of engineering project.
The main goal of this project was to build a standalone air/weather monitoring station while at the same time learning as much as possible about digital electronics and FPGAs.
The project is split into five parts:
- device programming (FPGA configuration) in VHDL (Quartus Prime LE 17.2)
- archiver and user interface in Python (3.x)
- device API binding for Python
- custom PCBs designed for the project (KiCad 5.x)
- intermediate build stages of the device programming with "unit" test benches
The measurement device was built using the following parts:
