The student group's friendly 4.0 trash can help sort out the garbage correctly

The trash can welcome and say goodbye to the people who came to waste. In particular, with the built-in sensor, the trash will only open when the person who put the garbage in the correct bin.

This friendly trash is the creative product of Nguyen Anh Thu and Nguyen Van Loi (students of Phu Dien Secondary School, Phu Vang District, Thua Thien Hue) with the guidance of teacher Tran Van Vu.

Talking to the Discovery Magazine, Vu said that this product has been applied to classrooms, school grounds, canteens, families . In addition, the product has also appeared in the 'Sundays. Green ' locally, helping people to protect the environment for the whole society to add Green - Clean - Bright.

According to Anh Thu, waste treatment in Vietnam is mainly carried out in the form of collecting and burying in landfills, not focusing on the collection and classification of garbage for reuse.

Currently, in the province of Thua Thien Hue, is exciting the 'Green Sunday' movement to help the province add Green - Clean - Morning. This is an opportunity for everyone to join hands to protect the environment.

'We conduct research on a friendly trash project to raise people's awareness about waste separation at source, reuse waste, contribute to limiting waste to the environment, because this is cause of climate change and disease ' , Thu shared.

After setting up the idea, you proceed to find materials, then program, connect and operate. You have to give a suitable drawing so that the doors open up to the idea that the three teachers and students put forward.

Loi said that when turning on the power switch, all the circuits in the trash system are active. When someone comes to remove the 30cm distance, the bin will automatically greet.

'When we put all the rubbish in the trash, there are 2 compartments on the bin for us to distinguish metal and other trash from asymptotic metal sensors and infrared sensors on each compartment' , Margins Introduction

When we hold the metal into the compartment for other garbage, the sensor receives a metal signal so the circuit does not work, the door is not open. At that time, we put in the first compartment, the metal sensor received the signal for the working circuit, the door opened and put the garbage into the bin.

Similarly, when we take other types of garbage into compartment 1, the metal sensor receives the garbage signal that is not metal so the circuit does not work, door 1 does not open. At this point, we put in the No. 2 compartment, the sensor that receives the control circuit signal opens the door, put the garbage into the bin.

Not only that, when the garbage person left, the trash would say goodbye. When the trash is full, the infrared sensor receives the full signal by the RF signal that we have placed in the house or the red flag room is 100 meters away, the indicator light is up, we take the garbage to the garbage disposal site .

The letter added: 'The product has used 4.0 technology such as using infrared sensors, metal sensors to sort out garbage; Using solar batteries, can supply electricity to storage batteries to supply all the circuits in the trash '.

This product has won the Second Prize of the Youth and Children of Dong Nai provincial competition in 2019, the fourth prize of the provincial Science and Technology Competition in 2019.

Talking about his students, Mr. Vu said, in order to produce this product, Thu and Loi were highly concentrated, doing their best, they were very good and gifted in creativity.

'Garbage can work well, students are very excited to put garbage in the bin. If you get the attention, support and support of companies, the product will be replicated for use in the whole province or across the country. In order for this talent to help every citizen consciously classify garbage from family, school and public , 'Mr. Vu shared.
