[0002] Garbage is solid waste generated in human daily life and production. Due to its large discharge volume and complex and diverse composition, garbage disposal becomes complicated and difficult. If it is not handled in time or handled improperly, it will cause serious environmental pollution and affect people's living environment. Garbage disposal is to quickly remove the garbage, treat it harmlessly, and finally make reasonable use of it. However, the most common treatment method so far is sanitary landfill. Although this method can be degraded by microorganisms in the soil, it takes a long time and is prone to odor and even fire. There are high unsafe factors. Therefore, we propose a household garbage classification system based on the Internet of Things.

[0003] Especially when garbage cannot be sorted, the garbage is mixed, which is not only not conducive to cleaning, but also easily causes larger-scale pollution. Summary of the invention
