Technical extensions
Official BME280 data: combined relative-humidity, absolute barometric-pressure and ambient-temperature sensing; humidity range 0–100% RH, accuracy tolerance ±3% RH and hysteresis ≤2% RH; pressure range 300–1100 hPa and 0.2 Pa RMS noise; temperature range −40…+85 °C. Typical current at 1 Hz: 1.8 µA for humidity/temperature, 2.8 µA for pressure/temperature and 3.6 µA for all three; sleep current 0.1 µA. Pressure sensitivity error ±0.25%; pressure temperature coefficient ±1.5 Pa/K. Bosch specifies the metal-lid LGA package but does not state an IP rating.
