# Plantower sensor library for node

## Install

```javascript
npm install hazyair-plantower -g
```

### Commandline usage

```bash
plantower -d /dev/ttyS0 -m PMS5003S
```

Example output:
```

concentration_pm2.5_normal:    8 µg/m^3
concentration_pm10_normal:     8 µg/m^3
concentration_pm1.0_atmos:     6 µg/m^3
concentration_pm2.5_atmos:     8 µg/m^3
concentration_pm10_atmos:      8 µg/m^3
count_pm_0.3:    1158
count_pm_0.5:    319
count_pm_1.0:    36
count_pm_2.5:    1
count_pm_5:      0
count_pm_10:     0
formaldehyde:    0.006 mg/m^3
```

## Programming usage

```javascript
const Plantower = require('plantower');

let plantower = new Plantower('PMS5003S', '/dev/ttyS0');

plantower.read().then(console.log.bind(console)).catch(err => {
    console.error('error when read data, err=' + err);
});
```
