M5Stack TVOC/eCO2 Unit (U088) – air quality sensor (SGP30)

The TVOC/eCO2 unit measures volatile organic compounds in the air (TVOC): what comes from cooking, cleaning products, new furniture and people in a room. It gives a good picture of when it is time to air the room.

Good to know

The eCO2 value is calculated from TVOC, not measured carbon dioxide. If you want to measure the real CO2 level, choose the CO2 Unit (U103) with the Sensirion SCD40. The SGP30 needs to run for a while after start-up before readings settle.

Works with

• ESPHome (component sgp30)
• Home Assistant via ESPHome
• All M5Stack controllers with a Grove port

You also need

A controller, for example the AtomS3 Lite. Grove cable included.
