== Summary ==<br />
The BME68X environmental sensor measures temperature, humidity, barometric pressure and gas resistance via I2C or SPI. It is supported on Raspberry Pi, Arduino, ESP32 and Pico; IAQ calculation requires the non-open-source Bosch BSEC software library.<br />

<br />
== Technical overview ==<br />
* Four-in-one sensing: temperature, relative humidity, barometric pressure and VOC gas resistance in one module.<br />
* Communication via I2C (default) or SPI; I2C address configurable via ADDR pad (0x77 default, 0x76 when grounded).<br />
* Onboard voltage translator supports 3.3 V and 5 V supply.<br />
* BME680 and BME688 include a mini MOX sensor whose resistance changes with VOC concentration.<br />
* An IAQ value (0–500) is only produced through the official, non-open-source BSEC library; use is subject to Bosch licensing restrictions.<br />
* Module dimensions: 27 mm × 20 mm.<br />
* Platforms covered in the wiki: Raspberry Pi (C/Python), Raspberry Pi Pico, Arduino, ESP32.<br />
* Stated measurement ranges: temperature −40 to 85 °C, humidity 0–100 % r.H., pressure 300–1100 hPa.<br />

== Notes and version constraints ==<br />
* The BSEC library is proprietary and license-restricted; review licensing terms before integration.<br />
* I2C address depends on the ADDR pad state; if malfunction occurs, check connection, communication mode and address.<br />
* Demo files must be downloaded and extracted; paths may vary by version.<br />
* Arduino SPI demo uses D10/D11/D12/D13; other boards require adjusted pin assignments.<br />
* No warranty or certification information present in the source; no safety notes available.<br />
