Design and realization of paper goddess self-service vending machine
With the development of society and the improvement of people's living standards,sanitary pads have become an essential physiological item for women.The traditional offline sales model has many problems such as time constraints and privacy issues.The article proposes an automatic selling mode based on the combination of STC89C52RC microcontroller and cloud devel-opment database,and designs and implements a self-service vending machine for sanitary cotton.The vending machine achieves the purchase of sanitary pads through scanning code payment,breaking the conventional sales model without the need for manual participation,making it convenient and fast.In addition,the vending machine is protected by using a vibration sensor,piezoelectric tapping vibration,and a buzzer.The feasibility and effectiveness of self-service vending machines have been verified through data analysis and practical testing.The article concludes by proposing future research directions such as further improving the function-ality and performance of self-service vending machines,with the aim of making them applicable to a wider range of scenarios.
