Sensirion SGP40: digital indoor air quality (VOC) sensor with VOC Index output, humidity compensation and I²C interface.
SGP40 is a digital VOC (volatile organic compound) sensor developed by Sensirion for indoor air quality applications. Using CMOSens® technology, it offers an I²C interface, a temperature-controlled micro hotplate and a humidity-compensated air quality signal on a single chip. Together with Sensirion’s VOC algorithm it delivers a VOC Index output from 0 to 500 and can be used directly in applications such as fan control in air purifiers.
Key features
