SMART SHOPPING CART USING ESP

Abstract

The Smart Shopping Cart is an innovative project that leverages the capabilities of the ESP32 microcontroller, along with various sensors and displays, to create a convenient and intelligent shopping experience. The system is designed to streamline the process of in-store shopping by automatically tracking and managing products as they are placed in the cart. ESP32-CAM: The heart of the system, responsible for controlling other components and performing QR code scanning. Ultrasonic Sensor: Used for object detection, triggering the camera to scan QR codes on products when they are placed in the cart. Buzzer: Provides audible feedback to indicate successful QR code scans and other system events. 128x64 OLED Display: Displays product information, scan status, and other relevant data to the shopper. Initialization: Upon starting, the ESP32-CAM connects to Wi-Fi and initializes the ultrasonic sensor, buzzer, and OLED display. Object Detection: The ultrasonic sensor continuously measures the distance between the sensor and objects. When a product is placed in the cart, the sensor triggers the camera. QR Code Scanning: The ESP32-CAM camera scans the QR code on the product, extracting its information such as name, price, and other details. Feedback: Upon successful QR code scanning, the buzzer provides an audible confirmation, and the OLED display shows product information and total cost.
