Solar Intelligent Water Dispensing system with voice control and Coin Integration https://www.hvstechnologies.in/product/hvs-4816-solar-intelligent-water-dispensing-system-with-voice-control-and-coin-integration/ https://www.hvstechnologies.in/product/hvs-4816-solar-intelligent-water-dispensing-system-with-voice-control-and-coin-integration/#respond Tue, 26 May 2026 13:33:40 +0000 https://www.hvstechnologies.in/?post_type=product&p=22212 This project presents an intelligent and automated water dispensing system designed to provide a convenient, contact-free, and user-friendly method for accessing drinking water. The system integrates coin-based operation, voice control, and glass detection to ensure accurate water delivery with minimal human intervention. A multi-coin sensor identifies ₹1, ₹2, and ₹5 coins and maps them to fixed dispensing volumes of 100 ml, 200 ml, and 500 ml respectively. After a valid coin is inserted, the system prompts the user to give a voice command through an Android mobile application via the HC-05 Bluetooth module. An IR sensor detects the presence of a glass to prevent spillage and ensure safety. The Arduino Nano serves as the central controller, operating the relay-driven DC water pump, while a 12 V rechargeable battery and solar panel provide clean and uninterrupted power. The LCD display offers real-time status updates such as coin detection, voice confirmation, and dispensing progress. This smart dispensing system enhances hygiene, reduces water wastage, supports renewable energy use, and is ideal for public places such as campuses, bus stands, hospitals, parks, and railway stations.

 

 

Objectives:

  1. To make a smart water dispenser that gives water automatically when a coin is inserted.
  2. To identify different coins like ₹1, ₹2, and ₹5 and give the correct amount of water (100 ml, 200 ml, 500 ml).
  3. To use voice commands so the user can say “water” to start the process after inserting the coin.
  4. To use an IR sensor to check if a glass is kept properly before pumping water.
  5. To use Arduino Nano to control all sensors, the motor pump, and the display.
  6. To show messages like “Insert Coin”, “Say Water”, and “Dispensing…” on the LCD display.
  7. To save electricity by using a solar panel and rechargeable battery to power the system.
  8. To provide clean, safe, and simple drinking water access in schools or public places.
