Design of an Autonomous Smart Shower With Sensors and Actuators
Design of an Autonomous Smart Shower With Sensors and Actuators is a scholarly work, published in 2018 in ''International Journal of Embedded Systems and Applications''. The main subjects of the publication include shower, electrical engineering, actuator, social norm, user experience, embedded system, computer science, and engineering. At the beginning of taking a shower, the user needs to manually adjust a rotational handle or the ratio of cold and hot water to get the desired water temperature and the flow rate.In this paper, a temperature and flow rate sensor feedback smart shower is proposed which takes the target water temperature and flow rate from the user as input, and then automatically adjusts the ratio of the cold and the hot water during the shower to keep the temperature and flow rate fixed -even though there is fluctuation of supply water temperature and pressure.The proposed system contains distance sensor and automatically turns off the shower when the user is away for soaping or shampooing.The system generates a report on water usage and shower timeto promote awareness on saving water.An embedded system based prototype of the proposed shower has been developed and tested.
