A Transducer Electronic Data Sheet (TEDS) is a standardized method of storing transducer (sensors or actuators) identification, calibration, correction data, and manufacturer-related information^[1]. TEDS formats are defined in the IEEE 1451 set of Smart transducer interface standards developed by the IEEE Instrumentation and Measurement Society’s Sensor Technology Technical Committee that describe a set of open, common, network-independent communication interfaces for connecting transducers to microprocessors, instrumentation systems, and control/field networks.

One of the key elements of the IEEE 1451 standards is the definition of TEDS for each transducer. The TEDS, in essence, is a memory device attached to the transducer and contains information needed by a measurement instrument or control system to interface with a transducer. TEDS can, however, be implemented in two ways. First, the TEDS can reside in embedded memory, typically an EEPROM, within the transducer itself which is connected to the measurement instrument or control system. Second, a virtual TEDS can exist as a data file accessible by the measurement instrument or control system. A virtual TEDS extends the standardized TEDS to legacy sensors and applications where embedded memory may not be available.

The goal of the IEEE 1451 family of standards is to allow the access of transducer data through a common set of interfaces whether the transducers are connected to systems or networks via a wired or wireless means. The 1451 family of standards includes^[2]:
