# Sensirion SCD30 CO2 sensor i2c driver module for Golang

## Overview

With this module Sensirion SCD30 CO2 sensor can be accessed throug i2c bus.

Implemented:

- starting and stopping continuous measurements

- checking for ready measurement

- reading ready measurement

- getting and setting temperature compensation

## Example

```go

package main

import (

	"log"

	"time"

	"github.com/pvainio/scd30"

	"periph.io/x/conn/v3/i2c/i2creg"

	"periph.io/x/host/v3"

)

func main() {

	if _, err := host.Init(); err != nil {

		log.Fatal(err)

	}

	bus, err := i2creg.Open("")

	if err != nil {

		log.Fatal(err)

	}

	defer bus.Close()

	dev, err := scd30.Open(bus)

	if err != nil {

		log.Fatal(err)

	}

	var interval uint16 = 5

	dev.StartMeasurements(interval)

	for {

		time.Sleep(time.Duration(interval) * time.Second)

		if hasMeasurement, err := dev.HasMeasurement(); err != nil {

			log.Fatalf("error %v", err)

		} else if !hasMeasurement {

			return

		}

		m, err := dev.GetMeasurement()

		if err != nil {

			log.Fatalf("error %v", err)

		}

		log.Printf("Got measure %f ppm %f%% %fC", m.CO2, m.Humidity, m.Temperature)

	}

}

```
