Garbage Monitoring and Disposal System for Smart City Using Iot

India's garbage generation stands at 0.2 to 0.6 kilograms of garbage per head per day. Also, it is a well-known fact that land in India is scarce. The garbage collector who comes to our house every morning to empty our dustbins inside his truck, takes all the garbage from our neighbourhood and dumps it on an abandoned piece of land. Garbage collectors from all parts of the city meet there to do the same. Such a land is called a landfill. India's per capita waste generation is so high, that it creates a crisis if the garbage collector doesn't visit a neighbourhood for a couple of days. As the procedure is purely manual, we need to implement a smart way of garbage monitoring and disposal. This paper proposes an IoT (Internet of Things) based approach for garbage monitoring and its disposal using ultrasonic and MQ4 sensors. Ultrasonic sensor checks the level of garbage filled in the biodegradable and non-biodegradable "smart bins".MQ4 sensors check the level of odour in the biodegradable garbage bin.After the threshold level is crossed in the non-biodegradable smart bin, the information is sent to the municipal corporation (with the help of an application) for the disposal of the garbage. If the threshold level is crossed in the biodegradable bin, a lid slides and the wastes are dumped in the underlying chamber. This method is more convenient than the manual one and is an initiative towards `smart city'. It ensures proper disposal of garbage and a restoration of a green and healthy environment.
