RFID-Based Smart Water Dispenser

RFID-Based Smart Water Dispenser

Description:

The “RFID-Based Smart Water Dispenser” is an innovative working model for students that demonstrates how RFID (Radio Frequency Identification) technology can be used to automate water dispensing. This project simulates a smart water management system where water is dispensed only when an authorized RFID tag is scanned, promoting efficient water usage and access control.

The model is constructed on a 40 × 50 cm Foam Board or Sun Board base, representing an automated water dispensing system. The system operates as follows:

Working Mechanism:

• RFID Tag & RF Reader:
  • A user taps an RFID tag on the RF reader to gain access to water.
  • The RF reader identifies the tag and sends a signal to the Arduino Uno microcontroller.
• Arduino Uno Microcontroller & Display:
  • Processes the RFID data and activates the water dispensing system.
  • A 16×2 LCD display module with I2C shows the user status and water availability.
• Water Dispensing System:
  • The relay module circuit controls the AC pump, which pumps water through the 12mm tube and L-bend mechanism.
  • A cut-off valve ensures precise water flow control, preventing wastage.
• Power & Connectivity:
  • A power distribution board supplies electricity to the circuit.
  • Jumper wires and 2-pin top connect all components securely.

Applications & Benefits:

• Reduces Water Wastage by dispensing water only to authorized users.
• Ideal for Schools, Offices, and Public Places where controlled water access is needed.
• Provides Hands-on Learning in RFID technology, automation, and smart resource management.
