Product Description:
The SGP30 Air Quality Sensor Module is a high-precision digital multi-pixel gas sensor designed to measure total volatile organic compounds (TVOC) and equivalent CO₂ (eCO₂) concentrations in the air. Built using Sensirion’s CMOSens® technology, the SGP30 offers superior long-term stability, low drift, and high sensitivity — ideal for applications like air purifiers, HVAC systems, and environmental monitoring devices.
This module integrates a fully calibrated sensing system in a compact enclosure, providing easy-to-use digital output through the I²C (IIC) communication interface. It can operate reliably under varying temperature and humidity conditions, making it suitable for indoor air quality monitoring, smart home devices, and IoT environmental sensing.
