An integrated circuit to drive a plurality of fluid actuation devices includes an interface, a first sensor, a second sensor, and control logic. The interface is to connect to a single contact pad of a host print apparatus. The first sensor is of a first type and is coupled to the interface. The second sensor is of a second type and is coupled to the interface. The second type is different from the first type. The control logic enables the first sensor or the second sensor to provide an enabled sensor. A voltage bias or a current bias applied to the interface generates a sensed current or a sensed voltage, respectively, on the interface indicating the state of the enabled sensor.
