Implementation of an ENS160 sensor driver written in rust. This sensor can measure `TVOC` and `ECO2`. Implementation is inspired by the [driver implementation](https://github.com/DFRobot/DFRobot_ENS160) by dfrobots written in python.

For more information about the sensor [here](https://wiki.dfrobot.com/SKU_SEN0515_Fermion_ENS160_Air_Quality_Sensor).

## Usage

To use this crate in a `no-std` environment, add it to your `Cargo.toml` as follows:

```toml
[dependencies.ens160]
version = "0.6"
default-features = false
```

## Example

```rust
let i2c = ...; // I2C bus to use

let mut device = Ens160::new(i2c);
device.reset().unwrap();
sleep(250)
device.operational().unwrap();
sleep(50)

loop {
    if let Ok(status) = device.status() {
        if status.data_is_ready() {
            let tvoc = device.tvoc().unwrap();
            let eco2 = device.eco2().unwrap();
            // from eCO2
            let air_quality_index = AirQualityIndex::try_from(eco2).unwrap();
            // directly
            let air_quality_index = device.air_quality_index().unwrap();
        }
    }
}

let i2c = device.release(); // destruct driver to use bus with other drivers
```
