The gravity sensing smart container solution is a smart retail terminal system based on gravity sensing technology and the Internet of Things. Through high-precision gravity sensors deployed in containers, the weight changes of goods are monitored in real time, and combined with cloud data analysis and mobile payment technology, automatic identification, non-sensing settlement, inventory management and user behavior analysis of goods are realized. This solution is suitable for unmanned retail, convenience stores, office shelves and other scenarios, and aims to improve operational efficiency, optimize user experience and reduce labor costs.
