sds011-rs

Rust crate for interacting with SDS011 particle sensor. Inspired by sds011_particle_sensor Python project.

This is my first Rust project, mostly as a learning exercise, so it's probably not very good or useful.

Dependencies

Rust
VS Code (optional)
- rls-vscode
- vscode-lldb

macOS

CH34x driver: CH341SER_MAC.ZIP
