Solar-Powered Hot and Cold Water Dispenser Using Peltier Sensor

Abstract

This research paper presents the design and development of a microcontroller-based water dispenser system utilizing Peltier modules for simultaneous heating and cooling functions. The objective of this project was to create a compact and energy-efficient solution that eliminates the need for bulky heating elements and air compressor setups commonly found in traditional water dispensers. The system utilizes an Arduino Mega microcontroller for controlling the operations and integrating various components, including a Peltier module, solenoid valves, coin accepter, ultrasonic sensor, temperature sensor, LCD, and relay module. The water dispenser allows users to select their desired water temperature and dispenses hot, cold, or normal-temperature water accordingly. The system incorporates a solar panel for sustainable power supply. Performance analysis of the water dispenser system demonstrated efficient heating and cooling capabilities, reliable operation, and user-friendly interaction. The results indicate the potential for energy savings and improved user experience compared to conventional water dispensers. This research contributes to the field of water dispenser technology by offering a compact, versatile, and environmentally friendly solution that can be applied in various settings, including households, offices, and public spaces.
