Sensors unit and air compressor system with such a sensors unit

A sensors unit for an air compressor system for supplying pressurized air for the medical and dental field, the sensors unit, in a mutual module housing, comprising:

• a) a pressure sensor configured to measure a pressure,
• b) at least one further sensor configured to measure another physical and/or chemical quantity,
• c) an evaluation and control unit comprising a microprocessor, the microprocessor configured to receive a signal from the pressure sensor of a pressure measurement and receive a signal from the further sensor of an other measurement of the other physical and/or chemical quantity, the evaluation and control unit further configured to provide measurement data of the pressure measurement and the other measurement, and
• d) an external interface for output of the provided measurement data,
• wherein the evaluation and control unit is configured to output the provided measurement data based on both the pressure sensor and the at least one further sensor in raw form and/or in processed form at the external interface, and wherein the mutual module housing comprises an outer end and a distal end, the distal end opposite the outer end, wherein the outer end is provided with a flange, the flange configured to connect the mutual module housing to a pressurized air tank, wherein the microprocessor is between the outer end and the distal end, and wherein the mutual module housing is configured to interact with the pressurized air.
