SENSOR MODULE

A sensor module comprises a master sensor unit (1) for sensing a first environmental parameter, a slave sensor unit for sensing (2) a second environmental parameter, a common substrate (3) on which the master sensor unit (1) and the slave sensor unit (2) are mounted, and a digital bus interface (4) for a communication between the master sensor unit (1) and the slave sensor unit (2). The master sensor unit (1) comprises a non-volatile memory (12) for storing calibration data and configuration data of the master sensor unit (1) and the slave sensor unit (2). The master sensor unit (1) is embodied as a first chip, and the slave sensor unit (2) is embodied as a second chip. Such sensor module is compact, robust and versatile.
