Project Description:

To design a smart water dispensing system for hostels that allows only registered users to access hot water using RFID-based authentication and ensures controlled and fair usage.Each user is assigned an RFID card. When a user scans the card on the system, the microcontroller checks the user’s ID against a preloaded list. If valid, the system activates a water heater and opens a valve to dispense hot water for a specific time or volume. After the limit is reached, it shuts off automatically. The system can also log usage and restrict repeated access within a time period.This smart hot water dispensing system provides a secure and efficient way to manage water usage in hostels. With RFID-based access and automatic control, it ensures fair usage, prevents waste, and reduces operational costs. It’s a practical step toward smarter hostel facilities
