BMP388 / BMP390 Temperature+Pressure Sensor¶
The bmp3xx
sensor platform allows you to use your BMP388 or BMP390
(datasheet, BMP390 product page) temperature and pressure sensors with ESPHome. The I²C bus is
required to be set up in your configuration for this sensor to work.

Oversampling Options¶
By default, the BMP3xx sensor measures pressure 16 times and temperature 2 times when requesting a new value. You can, however, configure this amount. Possible oversampling values:
NONE
(value is skipped)2x
4x
8x
16x
(default)32x
