This paper presents the design and implementation of an automated water cooler cleaning system using Arduino Uno and IoT-enabled components. The system addresses the challenges of manual cleaning and hygiene maintenance in water coolers by introducing a timed, sensor-based mechanism to facilitate periodic water circulation and drainage. A small tub is integrated within the cooler, where water is temporarily pumped from the main tank for the cleaning process. An ultrasonic sensor continuously monitors the water level in the tub to detect when the cleaning cycle is complete. Upon reaching a low-water threshold, the system automatically shuts off the circulation pump and activates a solenoid valve to drain the used water back into the main tank. A two-hour interval timer governs the repetition of this process, ensuring consistent maintenance without manual intervention. A push-button interface is provided to initiate or reset the cycle. The system is microcontroller-driven and designed for low-power operation, with potential for remote monitoring through a Wi-Fi module. This approach improves hygiene, reduces human effort, and enhances the operational efficiency of water cooling systems in public and domestic settings.
