Item Aplicação de controle PI e PID na construção para dispositivo de resfriamento: uma proposta prática(2023-09-29) Souza, Matheus Afonso Lima de; Neves, Cleonor Crescencio das; http://lattes.cnpq.br/2176855362313017; Reis, Ailton Gonçalves; http://lattes.cnpq.br/7119484789256081; Neves, Cleonor Crescêncio das; http://lattes.cnpq.br/2176855362313017; Reis, Ailton Gonçalves; http://lattes.cnpq.br/7119484789256081; Santos, Eliton Smith dos; Santos, Alyson de Jesus dos Santos; http://lattes.cnpq.br/5998752909180697This undergraduate thesis details the development of a prototype for temperature control in a closed environment using PID control techniques. The prototype, housed in an MDF box, regulates a 100-watt lamp via a dimmer to maintain the voltage at 33 Vac. DHT11 and DS18B20 sensors are employed to monitor internal and external temperatures. Real-time sensor data is collected and analyzed through MATLAB-generated graphs. Cooling is facilitated by a 12Vdc fan controlled through PWM signals from the ESP8266 and a BC458 transistor. The PID control implementation, using the Arduino's PID_v1 library, is fine-tuned based on open loop responses and COHEN & COON relationships. Results highlight the energy consumption for cooling concerning the external temperature, establishing an effective temperature control solution for controlled environments.Item Sistema automatizado para cultivo de plantas baseado internet das coisas(2023-09-01) Palheto Neto, Pedro Ivan Das Graças; Palheta, Pedro Ivan Das Graças; http://lattes.cnpq.br/1581213571653545; Neves, Cleonor Crescencio das; http://lattes.cnpq.br/2176855362313017; Palheta Neto, Pedro Ivan Das Graças; http://lattes.cnpq.br/1581213571653545; Neves, Cleonor Crescêncio das; http://lattes.cnpq.br/2176855362313017; Queiroz Neto, José Pínheiro de; http://lattes.cnpq.br/8055796489225138; Martiniano, Alexandre Lopes; http://lattes.cnpq.br/2232239320901259This work consists of developing an indoor greenhouse for growing plants through an automated system using the principle of the internet of things. Using the control of temperature variables, air and soil humidity and luminosity, using sensing connected to the ESP32 platform. The user is given control and access to the status of the greenhouse, providing an environment for quality cultivation and easy construction.
