Smart Bin -the hygienic solution for smart waste collection and disposal via IoT

In this era of development, the major threat we face from being a developed nation are the improper ways of waste collection and disposal. We do witness many of our major cities being dumped with wastes and not being treated properly which could lead to even more crucial health hazards. Thus, an efficient waste collection and management is essential for a clean, green and sustainable environment. This paper presents a proper method to monitor the filling of waste bins and their collection with the help of Internet of Things (IoT). The bin will be placed in all major garbage collection sites and will be monitored remotely from a center, say a municipality board. The system is implemented using an ultrasonic sensor which is connected to node MCU as to monitor waste bin garbage level. The Wi-Fi module is inbuilt in node MCU. The waste bin depth level and weight will be measured and sent via Node MCU Ethernet Shield with an Internet connection to the Cloud platform named Ubidots. The cloud platform stores the collected waste bin level data into IoT database and display the waste bin depth level on online dashboard for real-time visualization. The Ubidots Event manager gives a notification alert to garbage collector’s mobile phone via a SMS when the waste bin is nearly filled for immediate waste collection. If the collector fails to take initiative to collect the waste the driver responsible for the collection and disposal will be charged with a penalty. A driver who earns penalty more than three times will face the license cancellation. Therefore, the waste collection and disposal will be more centralized and responsible together with being more effective and systematic. The society will become hygienic and will be able to provide a green environment for a better tomorrow.
