Thus we here put forward a smart water dispenser system with water saving feature. If glass is removed during the process, system stops the water supply until glass is encountered. On detecting a valid tag the system now sends a signal to the controller who checks if glass is present and then it starts the motor to pour water in glass using motor as long the glass is present. The system has RFID Reader that is used to read particular tags and send information to microcontroller about valid tags. The microcontroller now processes the information sent by the sensors to determine if glass is present. The system uses IR sensors to detect presence of glass and then the sensors send a signal to the microcontroller. The system also senses if glass is placed at the counter to avoid water spoilage if there is no glass placed at the counter panel. The system is capable of fully automated water dispensing using solenoid tap and sensors. Here we put forward a fully automated RFID based water dispenser system using Arduino and Relay. It measures the temperature and pushes notifications to the user about water consumption. The smart water dispenser measures the weight of the available water in the dispenser and pops an alert when the water in the dispenser is about to finish. We present a case study of the smart water dispenser is with the aid of weight sensor, temperature sensor, and raspberry is built to assists the users and the water bottle suppliers by tracking the amount of water used in day to day activity. Physical objects connected with smart sensors provide data to make people's life easier. The rapid growth of the Internet of Things (IoT) changes humans life into a smart world.
