The paper presents a new approach to store and read
Transducer Electronic Data Sheets (TEDS) compliant with the
IEEE 1451.4 standard. The idea is to take the bit stream of the
TEDS structure and store it on a non-volatile, easy-to-read,
cheap support as is the case of 2D bar codes. The TEDS structure
can thus be stuck to the transducer case or printed on catalogues,
ready to be read anytime and anywhere by a scanner device.
Experimental tests involving a Pt100 and a semiconductor
temperature sensor are described to illustrate the concept. The
tests include the generation of TEDS structures, their conversion
to 2D bar codes and their reading back. The encoding is done
online using a free web service; the decoding is done offline using
a simple webcam and some image processing functions.
LabVIEW code is presented to illustrate the encoding and
decoding processes.
