This paper deals with Web sensors with particular attention to data structures and interfacing features described by IEEE1451 standard. A network architecture is proposed to reduce Web-sensor structural complexity. Transducer and electronic datasheets (TEDS) are directly interfaced to Internet through an HTTP-based protocol, that has been inspired by IEEE1451.2 Transducer Independent Interface (TII). Finally, a working prototype has been realized and some tests have been carried out to evaluate functionalities and real performances.
