Monitoring of waste is one of the problems of the present era as the traditional way of manually monitoring the waste is a cumbersome process. The process utilizes much human effort, time and resources which can easily be reduced to a significant level with the introduction of an automated disposal system. This work thus presents the design and development of a smart bin garbage monitoring system by measuring the garbage level in real time and makes notification where necessary via text message and LED indication.
The proposed system consists of ultrasonic sensor which measures the garbage level, an atmega328 microcontroller that controls the system operation. Hardware components were bread-boarded, soldered and various components (sub-units) put in case to form the system. The sub-units were galvanized and put to work using C++ programming language with Arduino IDE. The smart dustbin design was tested with garbage at different levels and the LED indication and SMS feedback were found to be successfully functioning.
