Smart bins for garbage monitoring in smart cities using IoT system

Abstract

Abstract It is predicted that by 2025 more than 75 billion IoT devices will be linked with internet. Due to technological development and increase in population, industrializationand urbanization, the entire countries should need to formulate ecological development schemes. In connection with this, many countries are endowing large amount of money towards building smart cities. In the proposed work an IoT integrated smart bin for Smarter Waste Disposal Systemis devised. The proposed system will consist of waste bin that are equipped with ultrasonic sensor to detect garbage fullness, Load sensor to measure weight of the garbage, GPS sensor to locate bin location and Gas sensor to measure hazardous gas emission from bin. These sensors are interfaced with ESP 8266 NodeMCU module which a microcontroller is having cost effective Wi-Fi microchip with complete TCP or IP stack. The ESP 8266 can communicate with Wi-Fi modems present in the smart city which are in turn connected with cloud using internet. The proposed system can send alert message to municipal authorities whenever the height of garbage in the bin is greater than threshold value and also stores the data in cloud for future action.
