Abstract
This design is based on the STC89C52RC single chip microcomputer and the integration of various multi-function modules to complete the overall system control. It is composed of the core modules of humidity detection, relay drive, metal detection, intelligent alarm, MQ-2 smoke sensor, infrared sensing, ultrasonic detection, etc. We collect specific information through ultrasonic testing, and LCD1602 displays the current status; an infrared sensor and a smoke sensor are used for relevant monitoring; a humidity sensor and metal sensor automatically remind us to classify and put garbage; a relay analog control trash can automatically open and close. The system has the characteristics of ideal performance, low cost, convenient design, simple structure, and intelligence. It has found a feasible solution for the current environmental pollution problem to do garbage classification and treatment. It can play an important role in smart homes, smart campuses, intelligent transportation, telemedicine, and other fields, and will have a broader market prospect and application fields.
