Resumo: | This study reports installation of a system to control temperature and velocity of the air in a medicinal plant dryer using a PIC16F877A microcontroller. The air velocity was monitored by an anemometer and controlled by a frequency inverter. The temperature was measured by LM35 sensor and controlled with a TRIAC. The microcontroller performed actions of PID that determines the pulse of a PWM signal, which turns on the frequency inverter and also the TRIAC. The comparison between the manual and automated controls showed that automatic method reduced energy consumption by 63 %. |

A velocidade do ar foi monitorada com anemômetro de conchas e o seu controle realizado com um inversor de frequência. A temperatura foi medida pelo sensor LM35 e o seu controle foi realizado utilizando-se um triac. com um microcontrolador realizaram-se ações de controle PID, que determinavam a largura de pulso de um sinal PWM, que acionava o inversor de frequência e, também, o triac. Foi realizada a comparação entre dois métodos de controle de velocidade: manual e automático. Verificou-se redução de 63 % no consumo de energia elétrica quando foi utilizado o método automático.Universidade Federal de Viçosa - UFV2011-04-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/octet-streamapplication/octet-streamhttps://periodicos.ufv.br/reveng/article/view/13410.13083/reveng.v19i2.148Engineering in Agriculture; Vol. 19 No. 2 (2011); 101-111Revista Engenharia na Agricultura - REVENG; v. 19 n. 2 (2011); 101-1112175-68131414-398410.13083/reveng.v19i2reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/134/111https://periodicos.ufv.br/reveng/article/view/134/3795https://periodicos.ufv.br/reveng/article/view/134/3796Prates, Mauro de OliveiraPizziolo, Tarcísio de AssunçãoMelo, Evandro de CastroRocha, Ronicely PereiraNicácio, José Vitorinfo:eu-repo/semantics/openAccess2023-01-19T12:50:32Zoai:ojs.periodicos.ufv.br:article/134Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T12:50:32Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false |
