> Sirs,

There is a 1997 final thesis for an engineer degree in my university
(Polithecnical University of Catalonia, UPC, http://www.upc.es). The autor was
Mr. Sala. This thesis used a TDR card for cable faults detection as a card for
soil moisture adquiring and processing device. The thesis also covered two
sensors design and prototipe construction. There is also a short publication
on that in a electronic specialized Spanish magazine: Sala, D. & Torrents,
J.M.. "Reflectometria aplicada a la medida de humedad en suelos". Mundo
electrÛnico, n. 281, pp. 64-66, nov. ISSN-0300-3787.
