# BMxx80 Device Family
|
||
|
|
|
||
|
|
## Summary
|
||
|
|
|
||
|
|
BMxx80 is a device family that senses temperature, barometric pressure, altitude, humidity and VOC gas.
|
||
|
|
|
||
|
|
SPI and I2C can be used to communicate with the device (only I2C implemented so far).
|
||
|
|
|
||
|
|
## Device Family
|
||
|
|
The implementation supports the following devices:
|
||
|
|
|
||
|
|
- BMP280 temperature and barometric pressure sensor ([Datasheet](https://cdn-shop.adafruit.com/datasheets/BST-BMP280-DS001-11.pdf))
|
||
|
|
- BME280 temperature, barometric pressure and humidity sensor ([Datasheet](https://ae-bst.resource.bosch.com/media/_tech/media/datasheets/BST-BME280-DS002.pdf))
|
||
|
|
- BME680 temperature, barometric pressure, humidity and VOC gas sensor ([Datasheet](https://ae-bst.resource.bosch.com/media/_tech/media/datasheets/BST-BME680-DS001.pdf))
|
||
|
|
|
||
|
|
## Usage
|
