The increasing population and technological advancements have created a high demand for drinking water. To address this challenge, a coin-based water dispensing system is proposed, using a microcontroller, coin acceptor, infrared and ultrasonic sensors, and GSM technology for status alerts. This system aims to provide safe drinking water, reduce water-related illnesses, and can be implemented in public areas.
