This project demonstrates an IoT-based app that enhances smart billing and quantity verification for retail, suggesting improved inventory management.
This project suggests making a smart, IoT-enabled app. This device connects directly to digital weighing scales via Bluetooth or Wi-Fi. This would reduce the need for extra microcontroller units. The system has three main functions—quantity verification, cooking assistance, and smart billing—that are meant to make retail, cooking, and inventory management more efficient. The quantity verification module makes sure that products or materials are measured and checked correctly, which makes it useful for inventory control and business transactions. The cook aid module contains a carefully selected database of recipes with fixed quantities for every ingredient. The app advances the weight of ingredients on the scale as food is made. This ensures that the baking processes are consistent and precise. Smart billing module also calculates how much goods are bought and based on the total generated bill a QR code for easy billing.
