This lesson covers smart, integrated, and intelligent sensors: the classification hinges on how much of the signal pre-processing (amplification, filtering, A/D conversion) and main processing (microprocessor-based decision-making, calibration, diagnostics, communication) is integrated onto the sensor chip. An intelligent sensor is formally distinguished by possessing at least one of: performing a logical function, communicating with other devices, or making decisions from crisp or fuzzy data — requiring an onboard processing unit. The domain is smart-sensor/mixed-signal-circuit theory within industrial instrumentation, covering integration architecture, self-calibration, self-testing, and multi-sensing redundancy.
