Description
Air quality sensor module based on the SGP40 system. The sensor is based on CMOSens® technology by Sensirion and uses a metal oxide (MOx) sensor. Provides indoor air quality information based on volatile organic compounds (VOC) with humidity compensation. Both the sensing element and the VOC algorithm are highly resistant to contaminating gases present in real-world applications, allowing long-term stability as well as low drift. SGP40 does not return specified concentrations or VOC gases. Instead, it generates a digital value based on typical VOC gases present in the indoor environment and this value can be combined with Sensirion's VOC index algorithm to detect the relative intensity of VOC events in relation to the average readings over a 24 hour period. SGP40 communicates via the I2C interface available on the Qwiic connector. Full documentation with examples of use is available in the guide.
