Solid waste management is a challenge for the cities authorities in developing countries mainly due to the increasing generation of waste, the burden posed on the municipal budget as a result of the high costs associated to its management, the lack of understanding over a diversity of factors that affect the different stages of waste management and linkages necessary to enable the entire handling system functioning. As a result it has become a challenge for the authorities to know the information of garbage full bins as they are many in number. Thus bin overflow could occur and may lead to bad odor at the surroundings which finally could spread dangerous diseases.
This project IOT Garbage Management system is a very low cost and an innovative system that provides a solution to the above discussed problem which will help to keep the cities clean and contribute for smarter cities. This system monitors the garbage bins and informs about the level of garbage collected in the garbage bins via the cloud platform over the internet. For this, the system uses ultrasonic sensors placed over the bins to detect the garbage level and compare it with the garbage bins depth. The system makes use of AVR family microcontroller, LCD screen, Wi-Fi modem for sending data and a buzzer. The system is powered by a dc 5V. The LCD screen is used to display the status of the level of garbage collected in the bins.
The cloud platform facilitates the data analytics and report generation options to view the status of the bins in various time stamps to the data centre monitoring it. It gives a graphical representation of the distance from the top of the bin to the garbage and highlights it in color in order to show the level of garbage collected. The LCD screen interfaced to the system shows the quick status of the garbage level. The system puts on the buzzer when the level of garbage collected crosses the set limit. Also the data is pushed to the cloud platform in regular intervals for further analytics. Thus, the system helps the authorities to know the bin status in the city from remote place, concerned teams can be automatically intimated with the status of filled bins to further clear and clear the garbage.
