The DFRobot Gravity: SGP40 Air Quality Sensor is a VOC sensor module with Sensirion SGP40, I2C interface, and 3.3 V to 5 V supply. It provides a VOC index from 0 to 500 and a measuring range of 0 to 1000 ppm ethanol equivalent at 2.6 mA operating current. More product details

Product Description

The DFRobot Gravity: SGP40 Air Quality Sensor is a compact VOC sensor module for indoor air quality evaluation. It is based on the Sensirion SGP40 and uses a digital sensor architecture with a temperature-controlled micro-hotplate and a humidity-compensated air quality signal.

The module communicates via I2C and operates from 3.3 V to 5 V. In combination with Sensirion’s VOC algorithm, the sensor signal can be used directly for air quality evaluation. The specified VOC index is derived from the detected ethanol equivalent in air. With a low operating current of 2.6 mA, a response time of 2 s, and a preheat time of 10 s, the module is suitable for long-term indoor monitoring applications.
