Frequently Asked Questions

What is the default I2C address and how do I change it?

The default I2C address for the BME680 on this breakout is 0x76. The address is typically fixed by the Bosch sensor IC and is not user-configurable on this module. For systems requiring multiple I2C devices, use an I2C multiplexer or select a different sensor model with an alternate address.

Can I use this sensor with both 3.3V and 5V Arduino or Raspberry Pi boards?

Yes. The breakout includes an onboard voltage regulator and an I2C level translation circuit, making it fully compatible with both 3.3V and 5V logic microcontrollers. For SPI communication, ensure your microcontroller's SPI pins operate at 3.3V logic levels when using the non-I2C connector pins.

What does the IAQ output represent and how is it calculated?

The IAQ (Indoor Air Quality) output is an index from 0 to 500 calculated by the BME680's internal algorithm based on detected Volatile Organic Compounds (VOCs) and other environmental parameters. A lower score indicates better air quality. The sensor requires an initial burn-in and calibration period of several hours to provide stable, accurate IAQ readings.

What is included in the package and do I need to solder headers?

The package includes the BME680 breakout board, one 4-pin single-row header, and one 6-pin single-row header. You will need to solder the appropriate headers onto the board to connect it to a breadboard or wires. The headers use a standard 2.54mm pitch.
