KEHIPI 2PCS SGP30 TVOC eCO2 Air Quality Sensor Module

SKU CH-V41E-RBKZ4

Pack of two I2C sensor modules measuring TVOC and equivalent CO₂ with a 2 V–5 V supply

  • In the boxOthers
  • I2C interface works with 2 V to 5 V systems
  • Direct drop-in replacement for CCS811 sensors
  • Measures TVOC and equivalent CO2 levels
  • Metal construction resists wear and corrosion
  • Two modules included for multi-point monitoring

Two-Module Air-Quality Kit

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.

Makers Adding Basic IAQ Sensing

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.

I2C Interface with 2–5 V Supply

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.

Questions about this item

How does the I2C interface on the SGP30 module limit data throughput in practice?

The I2C bus communicates at standard speeds; the SGP30 returns TVOC and eCO2 readings each time the master polls the sensor address.

What physical space and mounting method does the GY-SGP30 board require?

The module uses a compact PCB with header holes; it fits on a breadboard or can be screwed down via its mounting holes.

How is the sensor wired to an Arduino, and which connection step is often missed?

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.
