Seeed Studio Grove BME680 Temperature Humidity Pressure Gas Sensor
Four-in-one MEMS sensor measures VOCs, temperature, humidity and pressure with ±3% humidity and ±0.6 hPa pressure accuracy over a −40 to +85 °C range
- Product typeSensors
- 4-in-1 environmental sensing with temperature, humidity, pressure and gas detection
- High-accuracy humidity readings at ±3% between 20 and 80 % r.H. at 25 °C
- Pressure accuracy of ±0.6 hPa absolute and ±0.12 hPa relative
- Wide operating range from -40 to +85 °C, 0-100 % r.H., 300-1100 hPa
- Grove unified socket for plug-and-play integration with 3.3 V or 5 V systems
Environmental sensor for Arduino and IoT
The Grove BME680 module combines temperature, humidity, barometric pressure and gas detection in a single 40mm x 20mm board. It operates from 3.3V or 5V and communicates over a unified Grove socket for plug-and-play integration. The MEMS device weighs 9.1 g and is rated for -40 to +85 °C ambient conditions.
Upgrade from single-function sensors
A discrete temperature or humidity sensor only captures one parameter, while this module delivers four simultaneous readings with ±3 % r.H. humidity accuracy and ±0.6 hPa pressure accuracy. The jump is worth it when an application needs VOC monitoring alongside climate data without adding multiple breakout boards.
Fits 3.3 V or 5 V microcontroller builds
The board connects directly to a Grove-compatible host, freeing the developer from level-shifting circuitry and separate I²C wiring. Its 0.008 % r.H. humidity resolution and 300–1100 hPa pressure range support indoor air-quality stations, weather logging and altitude-assisted GPS projects. Buyers who need a smaller footprint or lower power draw than 9.1 g should evaluate alternative form factors.

Questions about this item
What size opening does the 40 mm by 20 mm board need for mounting?
The sensor board measures 40 mm by 20 mm by 7 mm and weighs 9.1 g, so plan a cut-out or bracket that clears those dimensions.
Which Grove cable and voltage setting should I use for the first connection?
Plug a standard Grove cable into the unified socket; the module accepts 3.3 V or 5 V supply, so match the controller voltage you are using.
How often should the gas-sensing element be recalibrated for VOC readings?
The BME680 MEMS sensor has no user-replaceable filter; long-term drift is corrected in software by periodic baseline calibration against fresh air.
