"Webb22 dec. 2014 · Sensor hub arrangement. In this scenario, there are two I²C buses. Let's call them local bus and main bus. The purpose of the local bus is to connect a bunch of sensors to a microcontroller (μC). The purpose of the μC is to poll the sensors, aggregate information from them, and detect certain events. A μC in such role is called sensor hub. " - I2c bus hub
