Abstract
A sensor device for measuring a physical value includes a sensor element for generating an output signal in response to measuring a physical value. A processor is operable with the sensor element for comparing the output signal to a reference signal in order to generate a primary signal indicative of the measured physical value. The processor is further operable with the sensor element for generating a secondary signal based on the output signal which is indicative of the operating condition of the sensor device. A switch or logic block is operable for receiving the primary and secondary signals from the processor. The switch and the logic block are switchable between a first state in which the primary signal is output and a second state in which the secondary signal is output.
