Regulador de temperaturas para chuveiros elétricos

Abstract

The project consists in implementing a temperature regulator for eletric showers where the user will choose the desired water temperature and the system will perform the power control of the shower until the selected temperature is reached. The regulator uses a temperature sensor, electronic components, and a microcontroller. An Integral Proportional controller, which takes the steady state error to zero, was used. Furthermore, due to the presence of transport delay, it was used a Smith Predictor which has the main advantage of eliminating the dead time of the control loop, improving the efficiency of the regulator used. With the temperature controller, the temperature of the bath is regulated, providing comfort, regardless of whether the temperature variation in the water feeding the shower, and reduce waste of resources like water and energy.
