Group 25 - Waste Management Idea

Denne idé er en del af VIA INO21 Challenge 4: Tech-Innovation - Smart Solutions For Waste Management In Public Spaces

8. februar 2021

The idea is based on a retro-reflective sensor in the trash bin that will detect the passing trash falling in the bin. When the emitter and receiver’s connection is interrupted for a longer time, this would mean the trash can is full and will be locked/closed until emptied. When this occurs, the Arduino app will send its ID and information to the server, after which the server will be able to notify the garbage collector’s system, that there is a full trash can with the specified ID. The trash collection company will now be aware that one of the locations is full. This information may be later used for designing better trash collection paths, optimizing the locations of the trash cans/containers, and extracting data such as the daily trash frequency. The two mechanisms, that the sensor needs to have for this solution to be operable are an Arduino Ethernet Shield, that connects the Arduino App and Drivers to the internet (which means it can send data to the server), and an actuator component that can lock the lid of the bin until the garbage collectors unlock the mechanism through an NFC connection. It is important to note, that there are a lot of different types of actuators and the most suitable needs to be chosen. One of the problems, which needs to be tackled is waterproofing the Sensor and Reflector surfaces, to remove the possibility of the components breaking down due to the liquids being thrown in the bin. One solution could be using a waterproof photoelectric sensor, but the reflector part remains unknown.


The idea was developed based on surveys and background research conducted, which showed the need for previously described product.
