Enumeration Type Documentation

◆ BME280IIRFilter

enum esphome::bme280::BME280IIRFilter

Enum listing all Infinite Impulse Filter values for the BME280.

Higher values increase accuracy, but decrease response time.

Enumerator
BME280_IIR_FILTER_OFF
BME280_IIR_FILTER_2X
BME280_IIR_FILTER_4X
BME280_IIR_FILTER_8X
BME280_IIR_FILTER_16X

Definition at line 52 of file bme280.h.

◆ BME280Oversampling

enum esphome::bme280::BME280Oversampling

Enum listing all Oversampling values for the BME280.

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