# Pi 4 particulate-matter (PMS7003) module Python dependencies (exact version pins for air-gapped networks)
# Offline install: pre-download into wheelhouse/ with vendor.sh, then
#   pip install --no-index --find-links=wheelhouse -r requirements.txt
#
# pyserial is pure Python (arch-independent py3-none-any wheel), so even if fetched on an x86 build
# machine it runs as-is on Pi 4 (aarch64). requests is version-pinned as well.
