Behavioural mixed-signal modelBME280 breakoutbme280
BME280 (temperature, pressure, humidity, I²C)
Bosch BME280 on a module (3.3 V regulator, pull-ups): temperature, air pressure, humidity via I²C (0x76, solder bridge 0x77). The environment is adjustable in the inspector, also during simulation; the sensor delivers raw values such that the datasheet's compensation formulas yield exactly these values.

Simulation model
A behavioural model implements the interface of the chip (registers, protocol, timing) at its pins. The pins are connected to the analog circuit like CMOS pins.
