Garbage management is one of the challenges experienced by most cities and towns today and this is due to poor management of garbage collection. Environmental sanitation is very important for heathy communities and living. In most of our societies waste bins are kept without proper monitoring until they are filled to the extent of overflowing and spilling out to the surrounding. This poor management leads to spread of garbage in communities which in turn leads to unhealthy conditions in the community, stimulation of diseases and degrades beauty of the area. For smart cities, waste bins need to be monitored and controlled to ensure healthy and clean communities and with the present technological advancement, real time control and monitoring of waste disposal is a challenging area that greatly needs intervention. The traditional approach of monitoring waste in waste bins placed in cities and towns is very tedious and an inefficient way that is time consuming, requires too much human effort and cost which contradicts smart city requirements. To improve on garbage management and cleanliness of the society, this project presents the design and development of an IOT automatic garbage monitoring system with Arduino microcontroller working with the ultrasonic sensors that detect the level of waste in the garbage and constantly at regular intervals displays the weight and level status on an OLED screen, as well as send the content information to a web page that displays the garbage level and weight. A message alert would also be sent as a notification in case threshold values of both weight and level were exceeded plus a buzzer that notifies people not to add in garbage. This was achieved using Arduino Nano microcontroller, a WI-FI module, GSM module, weight sensor and ultrasonic sensors. The prototype was designed and simulated using Proteus 8.0 professional simulation software and thereafter developed on a printed circuit board. Experimental results demonstrated a promising solution to garbage monitoring since a couple of testing runs were carried out to evaluate the prototype workability in real situations. The measured parameters (level and weight) from the garbage bins were transmitted to the web page; this web page performs visualization of the bin status showing the level and weight of the garbage in real time for viewing. The designed and developed prototype is therefore an innovation that will help improve on garbage monitoring and control thereby promoting smart, clean and well managed cities.
