# Sensirion SGP41 Driver
Platform agnostic Rust device driver for Sensirion SGP41.

[![Rust](https://github.com/aectaan/sgp41/actions/workflows/rust.yml/badge.svg)](https://github.com/aectaan/sgp41/actions/workflows/rust.yml)

This library provides an embedded `no_std` driver for the [Sensirion SGP41 sensor](https://www.sensirion.com/en/environmental-sensors/gas-sensors/sgp41/). This driver was built using [embedded-hal](https://docs.rs/embedded-hal/) traits. The implementaion is based on [scd4x](https://github.com/hauju/scd4x-rs.git) and [sgp40-rs](https://github.com/mjaakkol/sgp40-rs.git).

## Sensirion SGP41

The SGP41 is Sensirion’s new VOC and NOx sensor designed as digital smart switch and regulation unit for air treatment devices such as air purifiers.

## Usage

See an example using `linux-embedded-hal` in `examples/linux.rs`.
```bash
cargo run --example linux
```

## Development Status

The driver is in an development and testing state.  
VOC index scale and NOx index scale not implemented yet.
