Technical extensions
Pressure range: 300–1250 hPa. Official BMP384 data: absolute pressure range 300–1250 hPa; full-accuracy pressure range 300–1100 hPa at 0…65 °C; absolute accuracy ±50 Pa typical under those conditions; relative accuracy ±9 Pa typical at 900–1100 hPa and 25…40 °C (equivalent to ±0.75 m); pressure noise 0.03 Pa; temperature-offset coefficient ±1.0 Pa/K; long-term stability ±0.70 hPa/12 months; solder drift <±1.75 hPa; typical current 3.4 µA at 1 Hz and 2.0 µA in sleep; maximum sampling rate 200 Hz. The product page lists a 2.0 × 2.0 × 1.0 mm package, while the datasheet lists 2.0 × 2.0 × 0.95 mm; both source values are preserved here.
