Environment

Measure the atmospheric data around you.

NOTE: Only one environment module can be used at a time

Altitude	float	0 to 10km
SIAQ	float	0 to 500
SIAQ Accuracy	int	0 to 3
CO2	int	0 to 5000 ppm
VOC	int	0 to 5000 ppm
Stable	int	0 or 1
Start	int	0 or 1

What does the data mean?

Air quality measurements take about 30 minutes to calibrate. On first use it is suggested to allow the module to burn in for 48 hours.

SIAQ is better to use when the module is in one position while IAQ is better to use when moving.

CO2 is an estimation of the CO2 level and is a derivation from the average correlation between VOCs and CO2 in human's exhaled breath. VOC is a conversion into breath-VOC equivalents.

Right after the sensor is turned on it will go through a run in process. The values stay fixed for the first minute or two. This is the “.start” property. When it switches from 0 to 1 it is out of its power on run-in. There is an accuracy parameter “.siaq_accuracy” which ranges from 0-3. It will be 0 when it is running in for the first few minutes. The other parameter of .stable (0 or 1) is if it is undergoing initial stabilization during its first use. Accuracy increases the longer it is run as it has more values to compare against for internal calibration.

Altitude is calculated using a sea level pressure of 1013 hPA.

What ports can I use it on?

3-6

Code

Javascript

var celsius = Magic.modules.environment.temperature;

var stationaryIAQ = Magic.modules.environment.siaq;

var accuracy = Magic.modules.environment.siaq_accuracy;

var start = Magic.modules.environment.start;

Unity

using Magic;

public class Demo : MonoBehaviour
{
    // create a reference to the module
    public Magic.Modules.EnvironmentModule environment;
    
    void Start()
    {
    }
    
    void Update()
    {
        // access the property of the module
        float celsius = environment.temperatureC;
    }
