Grove - VOC and eCO2 Gas Sensor (SGP30)

This VOC and eCO2 Gas Sensor has dual-channel NDIR technology to detect carbon dioxide concentrations. Built with the Sensirion SGP30, a multi-pixel gas sensor, it is ideal for indoor air quality projects. Its low power consumption of just 48 mA at 1.8V provides excellent long-term stability.

It has high measurement accuracy thanks to its baseline compensation algorithm and on-chip calibration parameters. The Grove unified socket allows for easy "Plug and Play" integration, making it adaptable to a wide range of projects.

Powered by Sensirion’s CMOSens® technology, it has a complete sensor system on a single chip, with a digital I2C interface, a temperature-controlled micro hotplate, and two preprocessed indoor air quality signals. As the first metal-oxide gas sensor with multiple sensing elements on one chip, the SGP30 provides more comprehensive information about air quality.
