MÓDULO PARA REDES DE TRANSDUTORES INTELIGENTES UTILIZANDO O ATMEGA8

In start of decade at 90, the IEEE with NISTdeveloped a standard for development transducers networks.The standard does not define the type of hardware that willbe used or program language but the communicationinterface, protocols and TEDS (Transducer Electronic DataSheet). The TEDS are "tables" of data that there is theinformation of the transducers in format electronic. Today,the TEDS there are a format defined based on IEEE 1451.0standard, a specification appeared in 2007 for supportcommunication interfaces like RS232 (RecommendedStandard 232), UART (Universal AsynchronousReceive/Transmitter), SPI (Serial Peripheral Interface) andUSB (Universal Serial Bus). In this work is presented astudy feature of IEEE 1451.0 standard, protocols and TEDSspecifications. For analyze and studying was developed amodule TIM with temperature sensor LM35 based on IEEE1451.2 and IEEE 1451.0 where is presented in this paper.Index Terms ⎯ IEEE 1451.0, protocolo, comunicacao,interface, TEDS.
