Iot Based Smart Waste Management System Using Wireless Sensor Network and Embedded Linux Board

In many places, it can be seen that the Municipal garbage bins are overflowing and they are not cleaned at proper time. As a result of which the consequences are severe. It includes overflow of garbage which results in land pollution, spread of diseases. It also creates unhygienic conditions for people, and ugliness to that place. There should be a system that can monitor the bin and can give the information of filling of the bin to the municipality using wireless sensor network so that the bin can be cleaned on time and the environment can be safeguarded. This paper presents the Smart waste management system that identifies fullness of the bin using a wireless sensor network (WSN) and embedded Linux board and inform the authorized person for the cleaning of the bin. The system provides a web interface to the cleaning authority so that they can monitor and clean the garbage bin. In this paper, Raspberry Pi is used as an embedded Linux board which is designed based on the arm 11 microcontroller architecture. Embedded Linux board makes the communication with all distributed sensor nodes placed in the tested area through ZigBee protocol and itself act as a coordinated node in the wireless sensor network. The goal of coordinator node is to collect the parameters like level of the bin and odor wirelessly. Each sensor node consists of level sensor and gas sensors and one ZigBee RF antenna device for communication with the coordinator node. Raspberry Pi stores collected data in the database and analyzes the stored data. The board has an Ethernet interface and runs the simple data web server. Hence coordinator collects the data over ZigBee wireless communication protocol and allow user to monitor the data from a web browser. Cleaning authority can collect the garbage on time.
