![]() ![]() Forced mode ( low power operation): Performs one measurement, store results and return to sleep mode.Sleep mode ( Default): No operation, all registers accessible, lowest power, selected after startup. ![]() The BME280 offers three modes of operation: 4.35 - 15.95 PSI)įorced Mode Current Consumption: 4.2 ♚ (max)įorced Mode Current Consumption: 1.0 ♚ (typical) Temperature Measurements: 350 ♚ (peaks at 85☌)Ībsolute Accuracy: ☓ %RH (from 20 - 80 %RH)įorced Mode Current Consumption: 2.8 ♚ (max) Pressure Measurements: 714 ♚ (peaks at -40☌) Humidity Measurements: 340 ♚ (peaks at 85☌) Standby: 0.5 ♚ (inactive period of normal mode) (* IIR filter and oversampling can increase this to 20-bit excludes humidity data.) Sleep ( Default), Normal, and Forced ( low power single measurement) In the table below, are some of the characteristics of the BME280 sensor from the datasheet: Characteristicġ.71V to 3.6V ( Default on Qwiic System: 3.3V) The BME280 can be interfaced via I 2C ( used with Qwiic connections) or SPI communication. These modes dictate how the sensor performs measurement cycles. The BME280 uses three modes of operation: sleep mode, forced mode and normal mode. ![]()
