Abstract

Swachh Bharat Abhiyan (English: Clean India Mission and abbreviated as SBA or SBM for "Swachh Bharat Mission") is a national campaign by the Government of India covering 4,041 statutory cities and towns, to clean the streets, roads and infrastructure of the country. The aim of the mission is to cover all the rural and urban areas of the country to present this country as an ideal country before the world. With the proliferation of gsm technology, mobile phones, sensors, cameras it is possible to collect massive amount of garbage and separate the dry and wet dust automatically.

The littering of garbage bins makes serious unhygienic conditions in any type of surroundings. It leads to several health issues. To overcome this problem and make the waste management system more efficient and reliable, we need smart solution like smart waste management and hence that is designed in this project work. In this project, the type of waste (dry or wet) is monitored with the help of sensors (electrodes) and dumps it in appropriate chamber of the dust bin automatically. Microcontroller is interfaced with the GSM modem to transmit message to the concern municipality authorities when any of the dust bin i.e., dry and wet dust bins are completely filled. This will improve the segregation process.

Here a project is proposed to separate the dry waste and wet waste through the electrodes on the dumping plate that dumps the dust bin on either of the directions i.e., left or right where the dry and wet dust bins are placed to collect the dust. This can be useful to categorize the type of waste which is present in the dust bin. The proposed method of categorization is based on sensitivity of the dust material. The copper electrodes operated that are present over the top of the dust bin will identify weather it is dry or wet dust. Depending on this, the dust will separated by dumping it on to either of the side automatically. This information of the wet dust and dry dust full in their respective bins is sensed through the IR sensors that are connected to the arduino controller will be transmitted to the monitoring unit i.e., concern authorities via GSM modem. The project aim is to design an autonomous device that can separate dry and wet waste and alert the concern department automatically when any of the bins is full.

The microcontroller through DC motor will either rotate clockwise or anti-clockwise judging whether the dust is dry or wet. These electrodes provide the signal to the controller whether the dust is dry or wet. Depending on this, if the dust is dry it will be dumped to one side and if dust is found to be wet, it will be dumped to the other side automatically. A total of two sets of IR sensors for the dry and wet bins and a DC motor to dump the dust in the chamber are used in the project work. The controller allows dynamic and faster control along with the electro mechanical devices for the movement. This project uses regulated 5V, 500mA power supply. 7805 and 7812 three terminal voltage regulators are used for voltage regulation. Full wave rectifier is used to rectify the ac output of secondary of 230/12V step down transformer.
