Background With the improvement of social civilization, garbage classification has become an inevitable trend in the development of social civilization. But for various reasons, the implementation of waste classification is slow...
Problems of outdoor waste sorting device:
BAN Project 2 OUBAN
Failed to place correctly by category. In summer, mixing waste is easy to rot, stink and leak liquid. The transport vehicle occupies the lane and blocks the traffic.
Indoor and outdoor intelligent waste sorting device —— In China Date：2020/03-2020/05
Problems of indoor waste sorting device: The pets in the house always turn over the waste bin and make the waste everywhere. The elderly or children are not very clear about the types of waste. There is not so much space in the kitchen to put several waste bins and many waste bins in the living room affect the beauty.

Every week, residents have to push their garbage cans to the roadside and then the municipal departments will uniformly empty the disposal. Every household has to bear the cost of garbage collection and disposal.

3 The garbage truck carries the garbage to the garbage transfer station.
4 Garbage transf er station compresses garbage and loads it into containers.

Vehicle transportation: The truck can only dump all the garbage together and carry it away, thus losing the significance of garbage classification.
Set the entrance of garbage cans to different shapes The opening of the container for throwing bottles is designed as a small hole, and the container for throwing cardboard boxes is designed as an envelope.

Compost
Mature Simple operation and management technology low investment Save a lot of land. Make the harmless disposal of garbage more thorough. The heat generated by incineration can be used for heating and power supply. Low input in production. It can be used to produce agricultural fertilizer. Improving energy recycling efficiency.
Occupy a large amount of land resources. Easy to pollute groundwater and soil. Biogas is difficult to collect and dispose and easy to cause explosion. Easy to produce environmental pollution, such as dioxins, sulfides, etc. The cost of investing in building a factory is high. The pretreatment before incineration is complicated. Long time to dispose of garbage, poor capacity reduction of garbage. Applicable garbage scope is small, generally used for domestic garbage. The effect of composting is inferior to that of chemical fertilizer, and the enthusiasm of manufacturers is not high.

But I don't think that just investigating people's preferences for color can get effective results because each test object has different definitions of color and the surface material will also affect the user's visual experience. Therefore, I narrow the scope and render several choices for the user to choose.
The level of waste in the trash can can be detected by ultrasonic sensor. The sensor can be installed in the bin or bin and connected to the monitoring system, which can transmit whether the bin is full. When the height of the waste in the bin reaches a certain height, the red indicator light under the button will light up and then people will know it is time to replace the waste bag.

The object with low potential energy is relatively stable. When the tumbler falls, most of the center of gravity is concentrated. When the base is raised, the potential energy is increased, so the tumbler will return to its original position.

Users can plug in the power when they leave home. Charging for two hours can last for half a month.

The arm length of a normal person is about 60-70cm so the sensing range of the infrared sensor should be set at a radius of 120cm (1.2m)
Indicator
Navigation help people find garbage bin faster. Recognition tell the user which garbage bin to put. Pipeline transportation can reduce the workload of cleaners. Internal packaged garbage bags can be easily distinguished by color and label markings. Compared with vehicle transportation, pipeline transportation is not easy to cause pressure on traffic.
Image recognition technology may not be accurate enough. Classification equipment can only play an auxiliary role. It is important to improve people's classification and environmental awareness.
S S W O O
Improve the awareness, efficiency and accuracy of garbage classification from the source of garbage classification.
There are many smart trash cans with different functions on the market, which are highly competitive.
Many devices or apps on the market just tell you what the garbage belongs to. But my device will tell you which hole to throw into directly.
High-tech equipment may be difficult for the elderly to use.
