DESCRIPTION
The SparkFun SGP40 Air Quality Sensor provides a measurement of the quality of the air in your room or house. The SGP40 is based on Sensirion’s CMOSens® technology and uses a metal oxide (MOx) sensor with a temperature-controlled micro hotplate and provides a humidity-compensated volatile organic compound (VOC) based indoor air quality signal. Both the sensing element and VOC Algorithm feature unmatched robustness against contaminating gases present in real-world applications enabling unique long-term stability as well as low drift and device-to-device variation.
The SGP40 does not return specific concentrations of VOC gases. Instead, it outputs a digital value based on common VOC gases present in an 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 in a 24hr period. Think of the SGP40 as a sensitive electronic nose for detecting VOCs in a room.
The SGP40 communicates via I2C so SparkFun has broken out the pins on the sensor to Qwiic connectors so you can easily connect it to their ever-growing Qwiic Ecosystem!
