Abstract: This paper addresses the issues of poor management and delayed recovery in the old clothing recycling process by designing and implementing a monitoring and management system for recycling bins based on STM32 microcontroller, sensor technology, and WeChat Mini Program. The system integrates DHT11 temperature-humidity sensor, MQ-2 smoke sensor, HC-SR04 ultrasonic sensor, and HX711 weight sensor to achieve real-time monitoring of internal environmental conditions and clothing accumulation status within recycling bins. Leveraging Wi-Fi communication technology, the system transmits data to the WeChat Mini Program platform, enabling remote status monitoring and abnormal alarm notifications for management personnel. Experimental results demonstrate the system's stable operation, with advantages including low cost, low power consumption, and intelligent management capabilities. This solution provides an efficient and intelligent approach for old clothing recycling management, exhibiting promising application prospects in promoting resource recycling and environmental protection.
