Enumeration Type Documentation

◆ BMP280IIRFilter

enum esphome::bmp280::BMP280IIRFilter

Enum listing all Infinite Impulse Filter values for the BMP280.

Higher values increase accuracy, but decrease response time.

Enumerator
BMP280_IIR_FILTER_OFF
BMP280_IIR_FILTER_2X
BMP280_IIR_FILTER_4X
BMP280_IIR_FILTER_8X
BMP280_IIR_FILTER_16X

Definition at line 45 of file bmp280.h.

◆ BMP280Oversampling

enum esphome::bmp280::BMP280Oversampling

Enum listing all Oversampling values for the BMP280.

Oversampling basically means measuring a condition multiple times. Higher oversampling values therefore increase the time required to read sensor values but increase accuracy.

Enumerator
BMP280_OVERSAMPLING_NONE
BMP280_OVERSAMPLING_1X
BMP280_OVERSAMPLING_2X
BMP280_OVERSAMPLING_4X
BMP280_OVERSAMPLING_8X
BMP280_OVERSAMPLING_16X
