In this paper, we present an innovative Internet of Things (IoT) system designed specifically for retail applications, with a primary focus on enhancing operational efficiency and improving customer experience. Our system leverages NodeMCU as the central controller and integrates ESP32 for advanced human-following capabilities, offering a comprehensive solution to meet the diverse needs of modern retailers. Key features of our system include automatic billing and a human-following robot, both of which contribute to creating a transformative retail environment. The automatic billing component utilizes RFID technology and sensors to facilitate quick and precise transactions, streamlining the checkout process for both customers and retailers. NodeMCU, chosen for its enhanced connectivity and versatility, efficiently coordinates these functions, providing a robust platform for seamless billing processes. In addition to automated billing, our system incorporates a Bluetooth-controlled human-following robot powered by the ESP32 controller. This robot adds an interactive and futuristic element to the retail landscape, engaging customers in a novel and captivating manner. By intelligently tracking and following human movements, the robot enhances customer interaction and contributes to a more immersive retail experience. The integration of NodeMCU and ESP32 controllers addresses common challenges faced in the retail sector, offering improved connectivity, scalability, and advanced human-following capabilities. Real-world testing confirms the efficacy of our system, demonstrating its potential to redefine retail experiences through a combination of automated billing and cutting-edge human-following technology. By seamlessly coordinating these functionalities, our dual-controller system showcases the versatility and transformative impact of advanced IoT applications in the dynamic realm of retail. The result is an innovative and adaptable system poised to elevate efficiency, customer engagement, and overall retail experiences to new heights.
