What is the GY-SGP30?

The GY-SGP30 is an air quality monitoring sensor module that integrates the SGP30 multi-pixel metal-oxide (MOX) gas sensor. It measures Total Volatile Organic Compounds (TVOC) and equivalent CO₂ (eCO₂) by converting detected hydrogen and ethanol concentrations into these values. The module is designed for long-term stability and low drift, making it suitable for smart home devices, ventilation systems, and Internet-of-Things (IoT) air quality applications.

Key features

• The module accepts 3.3V or 5V supply voltage.
• I²C (IIC) communication interface for simple integration.
• Uses an imported high-sensitivity SGP30 sensor; the sensor chip operates at 1.8V.
• Compact, practical board design for easy mounting and integration.
• Typical power consumption: 40mA.
• Onboard 1.8V LDO regulator powers the SGP30 so the module can be driven from 3.3V or 5V inputs.

The GY-SGP30 provides a compact, reliable sensing solution for measuring indoor air quality indicators such as TVOC and eCO₂, and is appropriate for embedded systems where long-term stability and low measurement drift are required.
