IoT Based Smart Shopping Cart

By combining automation and real-time monitoring for increased convenience and safety, the Internet of Things-powered Smart Shopping Cart improves the in-store shopping experience. The device uses an Arduino-based controller and RFID technology for product tracking. Customers are alerted by a buzzer. When expired products are discovered, a siren and LCD display are also used by an expiry date detecting device to alert users. A NodeMCU (ESP8266) module installed in the cart allows cloud access using UBIDOTS for real-time alerts, such as notifications, special offers, and information on product expiration. By calculating the bill automatically and enabling digital payments, the system also expedites the checkout procedure. Here touch sensor is used as switch. If the customer decides to remove/add the product from the cart can use the Touch Sensor switch and remove the product from the cart. Through the integration of various technologies, the smart shopping cart increases shopping efficiency, improves customer safety, and offers a smooth, intelligent retail experience via email alerts and real- time notifications.
