Autor: Pedro Carvalhaes-Dias, Flávio J.O. Morais, Luís F. C. Duarte, Andreu Cabot, J. A. Siqueira Dias

Publikováno v: Applied Sciences, Vol 9, Iss 6, p 1211 (2019)

We present an autonomous sensor to measure soil water content that uses a single heat pulse probe based on a transistor encapsulated in a porous block. The sensor uses a bipolar junction transistor, which performs as both a heating and temperature-se

Response identification of air flow sensors using fuzzy system for embedded electronics

Autor: Kleber Romero Felizardo, Luís F. C. Duarte, André Sanches Fonseca Sobrinho, Francisco de Assis Scannavino Junior

Publikováno v: Measurement. 151:107070

This paper shows the development of a fuzzy system applied to low-cost microcontroller to assist in the identification of different intensities of air flow from the AWM2100 sensor, whose operation presents variation in the output voltage due to the v

Experimental Investigation on the Load Signature Parameters for Non-Intrusive Load Monitoring

Autor: Luís F. C. Duarte, Elnatan Chagas Ferreira, Alex Dante, Rodrigo M. Bacurau

Publikováno v: PRZEGLĄD ELEKTROTECHNICZNY. 1:88-92

One of the most important design decisions in Non-Intrusive Load Monitoring (NILM) systems is choosing which electrical parameters will be used to define load signatures. In this paper, we present an experimental study where several electrical quanti
