Pack of two I2C sensor modules measuring TVOC and equivalent CO₂ with a 2 V–5 V supply
This pack contains two SGP30 sensor modules that measure total volatile organic compounds and equivalent carbon-dioxide levels. Each board communicates over I2C and accepts a supply voltage between 2 V and 5 V. The modules are built from metal materials chosen for wear resistance and corrosion protection.
Hobbyists building Arduino-based air-quality monitors, ventilation triggers or data-logging projects will find the dual-module pack convenient for redundant or multi-room sampling. Developers who need calibrated formaldehyde readings, particulate-matter data or certified safety ratings should look at dedicated instruments instead.
The single specification that decides fit is the I2C interface combined with the 2 V to 5 V supply range; any host that cannot meet both electrical conditions will not work with these modules.

The I2C bus communicates at standard speeds; the SGP30 returns TVOC and eCO2 readings each time the master polls the sensor address.
The module uses a compact PCB with header holes; it fits on a breadboard or can be screwed down via its mounting holes.
Connect VCC to 2 V–5 V, GND to ground, SDA to A4 and SCL to A5; the step often missed is adding pull-up resistors on the I2C lines.
