SGP30_Gas_Sensor

This is a fork from Seeed SGP30_Gas_Sensor to make it compatible with Paricle. Please visit orginal repo for details about the sensor.

---

Usage:

Connect SGP30 hardware to the Particle board via the I2C ports, add the SGP30_Gas_Sensor_Grove library to your project. The sensor can be polled via the following code:

#include "Particle.h"
#include "sensirion_common.h"
#include "sgp30.h"

void setup()
{
    s16 err;
    u16 scaled_ethanol_signal, scaled_h2_signal;
    Serial.begin(115200);
    Serial.println("serial start!!");

    /*  Init module, reset all baseline,The initialization takes up to around 15 seconds, during which
        all APIs measuring IAQ(Indoor air quality ) output will not change.
        Default value is 400(ppm) for co2,0(ppb) for tvoc*/
    while (sgp_probe() != STATUS_OK)
    {
        Serial.println("SGP failed");
        while (1)
            ;
    }

    {

    }
    else
    {
        Serial.println("error reading signals");
    }
    err = sgp_iaq_init();
