Design and Development of Smart Tea/Coffee Vending Machine

In today’s fast-paced world, the demand for quick beverages like tea and coffee is soaring. Addressing this need, the Smart Tea/Coffee Vending Machine (TCVM) offers a modern, efficient, and eco-friendly solution. Integrated with QR code-based access control and IoT functionality, the system ensures secure, automated, and user-centric operation. Powered by a NodeMCU microcontroller, it supports real-time monitoring, inventory tracking, and predictive maintenance to minimize downtime and maximize efficiency. A dedicated mobile app allows access for authorized users only, while a multilingual LCD enhances user interaction. The machine features a 12V DC pump for accurate beverage dispensing and a 1.5L stainless steel electric kettle (230V, 1500W) with a Nichrome heating element for rapid heating. Designed for energy efficiency, it is both cost-effective and environmentally conscious. The TCVM promotes the use of reusable containers, significantly cutting down on single-use plastics. By blending automation with sustainability, this vending machine delivers a hygienic, energy-optimized, and user-friendly experience—perfectly aligning with the expectations of today’s consumers. It redefines beverage dispensing with its intelligent, reliable, and green design.
