VOC sensor includes control output and algorithm

· Sensirion's VOC algorithm analyzes VOC events detected by the SGP40 sensor and maps them to a VOC Index. This VOC Index provides a practical quantification of VOC events relative to each individual sensor's average indoor environment. The VOC Index indicates to what extent the indoor air quality has deteriorated or improved compared to the sensor's average VOC environment. This …
