Weather Aware Touchless Water Dispenser

Abstract— In addition to prevention against human touch, the desire for efficient and functional approaches to water dispensing has also lead to designs incorporating touchless designs, yet such approaches have largely missed the opportunity for adaptive-regenerative environmental systems. In this work, we present a touchless water dispenser that is weather-aware and actively adjusts water flow according to ambient temperature and humidity to enhance usage efficiency and user experience. They have also proposed a system that uses IOT in correlation with weather data which uses IoT based sensors, microcontrollers and cloud weathers data module and adjusts the dispensing patterns dynamically, thus minimizing the water use yet keeping up with hygiene. In contrast to traditional dispensers, that work only with proximity sensors, the proposed model takes adaptivity further by incorporating real-time weather analysis, which prevents over-consumption in cold regions and guarantees proper hydration in hot regions. A prototype was built and the results from its trials under a range of environmental conditions showed better than 20% efficiency improvement over the traditional sensor-based dispensers. Our findings emphasize the increasing role of weather-informed automation for smart hydration networks and the larger sustainable systems of automated water dispensing.
