Smart trash Bin

Trash of the same category will have almost the same electrical current (range); while waste with different categories will have a significant difference. Through this concept, researchers create sensors that can conduct electrical current, receive electrical current, and send it back to the microcontroller in the form of data. With this data, researchers created a microcontroller program to operate the bin automatically with the help of servo motors (open-closed) and set the range of data to detect organic, inorganic, and metal trash. Then, with the help of the program, the microcontroller can differentiate the waste by material and decide which lid will open. With this product, people are expected to be aware of the importance of waste processing, especially in sorting waste based on category. Furthermore, waste processing will become easier because the garbage has been sorted.
