Temperature remote monitoring using the 1-wireTM system: data transmission evaluation

Abstract

In industrial units of animal and vegetable protein production and processing, as well as in other sectors where the temperature monitoring is absolutely necessary, automatic monitoring systems that are capable to transmit accurate temperature data to long distances can contribute to increase the final products quality. Thereby, this work was accomplished with the purpose of evaluating the temperature data transmission of the 1-wireTM system by using low cost conductors which are widely commercialized for residential applications, with different types and lengths. The 1-wireTM system is a data transmission network that makes possible the digital communication between a computer and the devices of the 1-wireTM series, such as the DS1820 temperature sensors. Based on the results, it could be concluded that the telephonic conductors presented the best performance, making possible data transmissions up to 150 m
