Automatic Waste Bin with IoT System

Abstract

This research paper presents the design and construction of automatic waste bin with IoT system to create a modern waste bin that can be used in various places. It contains the following components: An ultrasonic distance sensing device, the processor system which consist of ESP8266 NodeMCU and the Arduino UNO R3 microcontroller. Notifications are sent to smartphones through the LINE application (Line Notify). All these devices work together as an IoT system. The working principle is as follows. When the automatic waste bin with IoT system starts an operation and there is movement near the waste bin within a predetermined distance. The distance sensing device will detect the movement, and then send the signal to the processor ESP8266 NodeMCU. This signal will trigger the servo motor to start its operation causing the lid of the waste bin to open so that users will be able to dispose of waste. Inside the waste bin, there is another distance measuring device that monitors the amount of waste in the bin. The amount of waste is displayed with LED lamps and a notification of the amount of waste in the bin can be sent to a smartphone via the LINE application, which is operated by the ESP8266 NodeMCU. The test results show that this automatic waste bin with IoT system can open the lid of the bin automatically at a predetermined distance and can display the amount of waste in the bin with LED lamps as well as can notify the amount of waste in the bin to the smartphone via the LINE application. It can be concluded that automatic waste bin with IoT system is different from general commercial waste bins, the bin with the lid opened by hands or feet, because the automatic waste bin with IoT system has an automatic detection system that eliminates the need for users to touch the waste bin as well as it can also notify the amount of waste in the bin to the smartphone via the LINE application. This notification is quite very useful for the waste collector in cases where there are multiple bins in different areas. This waste bin is suitable for use in hospitals, workplaces and other places that need to prevent contact with germs on the bin and help provide convenience to users.
