Abstract: This paper deals with effective usage of user TEDS for developing smart sensor readout which is suitable to estimate and compensate the disturbances occurring in the system. The system parameters are incorporated along with other transducer data. Appropriate processing capabilities are built in Transducer Interface Module TIM for disturbance estimation and compensation. A Verilog based single chip module of IEEE 1451.0 smart sensor is proposed incorporating the above mentioned features. The architecture enables reliable and smart readout for sensors at low cost for a given application. The programmable nature of the proposed architecture enables wide usage of the smart sensor for various applications.
