1. Specification
If not stated otherwise,
 All values are valid over the full voltage range
 All minimum/maximum values are given for the full accuracy temperature range
 Minimum/maximum values of drifts, offsets and temperature coefficients are ±3 values over
lifetime
 Typical values of currents and state machine timings are determined at 25 °C
 Minimum/maximum values of currents are determined using corner lots over complete
temperature range
 Minimum/maximum values of state machine timings are determined using corner lots over
0…+65 °C temperature range
The specification tables are split into humidity, pressure, and temperature part of BME280.
