Abstract
Smart faucet aims to reduce the wastage of water that happened in the bathroom while using a solar water heater for a bath. It also prevents the hot water scalds due to high temperature in showers and hot water taps. It controls the hot water temperature by mixing required cold water to bring down to user-defined temperature. Users can set the temperature value in the control unit and switch it either by the switch or by using the mobile application using IoT. It takes time to reach hot water in tap from solar water heater due to long pipeline connections. So much water is wasted and time too. Users can switch the unit and make it ready for use before entering the bathroom by using the mobile application. Unless Coldwater stored in the hot water pipeline is underground water storage for recycling. Smart faucet uses NodeMCU as a controller, temperature sensor, motorized ball valves, solenoid valves, temperature knob and relays for switching the solenoid valves. NodeMCU is incorporated with the android application called ‘Blynk’. It receives and sends data to NodeMCU so that the user can monitor all the parameters like flow rate, temperature, the quantity of water used and control the unit from the mobile. The motorized ball valve is used to regulate the water flow rate. So that the ratio of hot water to cold water can be achieved. These adjustments are carried out by means of the control unit as per the decision taken according to the temperature sensor value. In the meantime, the temperature required by the user can be taken as input by means of a potentiometer. By considering the user-defined temperature and temperature sensor signal, the angle of hot water and cold-water ball valve will be modified automatically to achieve the required temperature. The solenoid valve will open and close the line for draining purposes and for use. It acts as a direction control valve. All the above processes will carry out simultaneously once the user switch ON the unit. Hence wastage of water will be stopped and valve automation is achieved.
