An internet of things based smart waste system

Abstract

The importance of preserving the environment from waste and its pollution lies in many matters such as preserving people health, enhancing the aesthetic character of cites, attracting tourists, and protecting society from environmental disasters. The environmental wastes are the main dilemmas in our daily life and in the world at large. With the existence of modern technology, development and the field of the internet, many solutions have been undertaken to get rid these dilemmas. In this paper, a smart waste system based on internet of things (IoT) technique has been proposed using ESP-32 Wi-Fi microcontroller. This system can be adopted to avoid the accumulation of waste in the streets that distort the face of civilization, also to reduce the burden of workers and limit the workforce. The system is based on a multiple sensors in the garbage baskets, as they measure the waste level by using ultrasonic sensor, the moisture percent and temperature degree using DHT-22 sensor. The sensors data are processed by ESP32 microcontroller and displayed to both LCD screen using I2C protocol and mobile application using IoT cloud. System baskets automatically open their covers when the person approaches with a distance less or equal to 30 cm to throw garbage. Any approval waste basket is automatically discharged through an underground dump system using conveyor belt if the basket is full by 80% garbage and/or the basket moisture reaches to 40%.

Real-time monitoring system based on integration of internet of things and global system of mobile using Raspberry Pi

“…A digital platform enables the user to construct their own visual interface for the project according to their preferences. The user just has to drag and drop the widgets that are relevant to the sort of project they are working on in order to utilise it, making it a very user-friendly and straightforward piece of software [26]. This application is use in the IoT component.…”

Energy Internet-Based Load Shifting in Smart Microgrids: An Experimental Study

“…For this study, the controllers were implemented using Wi-Fi ESP32 MCUs, which possess two processing cores. The ESP32's Central Processing Unit (CPU) is a low-power Xtensa 32-bit LX6 microprocessor [36]. Moreover, the MCU is equipped with built-in wireless networking, Bluetooth, and Ethernet capabilities.…”

An internet of things-based pump and aerator control system

“…Several relevant studies are using the ESP32 module to implement IoT technology. Jasim et al [13] have proposed an IoT-based innovative waste system that can monitor the level and humidity of waste in baskets. Another purpose of such systems is to prevent the accumulation of waste by integrating each wastebasket on one rubber conveyor.…”
