Abstract

Disclosed herein are sensor circuits for a replaceable print material container, the sensor circuit to communicate with a printer logic circuit. An example sensor circuit includes a first sensor to detect at least one of a pneumatic stimulus or a pressurization applied by a printer, a second sensor, and an interface to communicate with at least one of a voltage source or a data source of the printer logic circuit. The example sensor circuit also includes logic circuitry, responsive to a class parameter, to: (a) output a first signal based on at least one of the pneumatic stimulus or the pressurization sensed by the first sensor when the class parameter is a first class parameter; and (b) output a second signal based on at least one of an output of the second sensor, different data, or a different algorithm when the class parameter is a second class parameter.
