What's Changed

• Add BME688 details to readme by @helgibbons in https://github.com/pimoroni/bme680-python/pull/47
• Bookworm/Pi5 Compatibility: Upgrade to latest boilerplate by @Gadgetoid in https://github.com/pimoroni/bme680-python/pull/50

New Contributors

• @helgibbons made their first contribution in https://github.com/pimoroni/bme680-python/pull/47

Full Changelog: https://github.com/pimoroni/bme680-python/compare/v1.1.1...v2.0.0

• New: constants to clarify heater on/off states

From 1.1.0:

• New: support for BME688 "high" gas resistance variant
• New: set/get gas heater disable bit
• Enhancement: fail with descriptive RuntimeError when chip is not detected

This release adds a new feature set_temp_offset for compensating t_fine before it's used for humidity calculations and converted to temperature. The compensation can be given in degrees C, and is converted automatically.

You should use this if your environment imparts a constant temperature variation upon the bme680 and you regularly read values with a consistent offset from a calibrated temperature sensor.

See https://github.com/pimoroni/bme680/issues/11 for details.

This release should fix problems reported in issue #6 - thank you to @lowflyerUK for spotting and fixing the error that caused these.

• Fix to range_sw_err for extremely high gas readings
• Convert to unsigned int to fix negative gas readings

This release should fix issues with temperature compensation in pressure readings. Thank you to @gkluoe for finding a bug in the Python port, and @jorisvervuurt for testing.

• Merged temperature compensation fix from Bosch's BME680_driver 3.5.3

See: https://github.com/BoschSensortec/BME680_driver/releases/tag/bme680_v3.5.3

• Fixed: added int() cast to set_gas_heater_temperature to avoid i2c TypeError
