What this sensor measures

The Sensirion SGP30 is a digital multi-pixel gas sensor designed for indoor air quality monitoring. It outputs TVOC levels from 0 ppb to 60000 ppb and equivalent CO2 readings. The module suits air purifiers, demand-controlled ventilation and new-house condition checks. It connects through a Grove unified socket for plug-and-play integration with microcontroller projects.

Power draw and thermal behaviour

The sensor supports 48 mA at 1.8 V, enabling low power consumption for long-term deployments. A temperature-controlled micro hotplate maintains stable operation across normal indoor conditions. Dual-channel NDIR technology and dynamic baseline compensation preserve measurement accuracy over time. No active cooling is required for typical use.

Build integration and constraints

The board measures 135 mm by 85 mm by 10 mm and weighs 9 g. It operates at 3.3 V or 5 V and communicates over a digital I2C interface. The Grove socket simplifies wiring for beginners and rapid prototyping. Buyers who need analog output or wireless connectivity must add separate modules.

Questions about this item

How do I connect the Grove VOC eCO2 sensor to my board and what step is often missed?

Plug the Grove cable into the unified socket and supply 3.3V or 5V; the step often missed is allowing the dynamic baseline algorithm time to stabilise before trusting readings.

What maintenance will the SGP30 sensor need over its life?

No user-replaceable parts are required; long-term accuracy relies on the on-chip calibration and periodic exposure to fresh air so the baseline compensation can update.

At what TVOC level does the sensor reach its measurement ceiling during sustained use?

The output range tops out at 60000 ppb TVOC, so concentrations above that limit will not be reported.
