Abstract – In response to the growing challenges of urban waste management, this paper proposes an innovative solution leveraging IoT technology and renewable energy sources. The IoT-based solar- powered smart dustbin presented here aims to enhance the efficiency and sustainability of waste collection processes in urban areas. The system incorporates ultrasonic sensors that continuously monitor the garbage level within the dustbin. Once the garbage level exceeds a predefined threshold, a real-time message is automatically transmitted to the municipal authorities, prompting timely garbage collection. This proactive approach minimizes overflow and littering, thereby improving overall cleanliness and sanitation in urban environments. Central to the functionality of the smart dustbin is its utilization of solar power for energy supply. Solar panels integrated into the design harness sunlight to generate electricity, ensuring continuous operation without reliance on traditional power sources. This not only reduces operational costs but also significantly diminishes the system's carbon footprint, contributing to environmental sustainability. Moreover, the implementation of IoT technology enables remote monitoring and management of the smart dustbins across multiple locations. Municipal authorities can access real-time data on garbage levels, collection schedules, and system performance through a centralized dashboard. This enhances operational efficiency, allowing for optimized resource allocation and proactive maintenance.

Efficient waste management possess a significant challenge in urban areas globally, requiring the implementation of well organised clearance system to uphold environmental sustainability [10]. The respective programmed logic is written in Arduino IDE and interfaced with ESP32 to detect the filling level of the dustbin through the ultrasonic sensor and sends a notification when it reaches a pre-defined threshold, signalling the need for disposal. IoT comprises interconnected physical entities assessable via internet, where the THING refers to tangible devices equipped with sensors, enabling them to transmit data via IFTTT platform and communicate autonomously with a central station.

    The integration of solar powered system holds immense potential for innovative projects such as a smart garbage system. Harnessing energy from sun not only aligns with sustainable practices but also enhances the efficiency and reliability of the waste management infrastructure. By incorporation solar technology, this system can operate autonomously, reduce dependency on conventional power sources and contributing to environmentally conscious solution for urban waste disposal.

    Ahmedy, I. Idris, M.Y.I. Soon, and T.K. Noor, they presented that In current systems, municipal authorities typically schedule regular trash collection using manual methods, leading to various challenges. These include uncertainty regarding the condition of specific sites, employees' lack of awareness about the demand for waste collection in particular areas, inefficiency in maintaining city cleanliness, and the necessity of assigning dedicated vehicles for trash removal. These challenges highlight the need for more advanced and efficient waste management solutions.

    A proposed solution involves implementing ultrasonic sensors to monitor real-time fill levels of bins, enabling data storage for future use in tasks such as optimizing collection routes and analyzing waste generation trends. Additionally, the bin design includes a feature where the lid automatically closes when the bin reaches full capacity, and a proximity sensor detects the presence of an employee for waste collection, as outlined in the design proposed by Aksan Surya Wijaya et al. This integrated approach enhances efficiency and effectiveness in waste management operations [7].


    When garbage overflows, citizens face a myriad of challenges that disrupt their daily lives and compromise their well-being. Firstly, the unpleasant odor emanating from the overflowing garbage becomes pervasive, permeating the air and causing discomfort to nearby residents, diminishing the quality of life for all inhabitants. This foul stench not only affects the immediate vicinity but can also spread to surrounding areas, detracting from the beauty of the environment and diminishing property values. Moreover, the accumulation of waste becomes a breeding ground for pests like flies and rodents, further exacerbating the problem, posing health risks and creating a sense of unease and insecurity among residents. Additionally, the health hazards associated with accumulated garbage cannot be understated, as disease-carrying organisms thrive in such environments, increasing the risk of illnesses and infections among residents, from respiratory issues to gastrointestinal problems. Similarly, the widespread adoption of renewable energy sources faces challenges such as technological limitations,

      Fig.2 Functional block diagram

      The solar panel connection for the Smart Trash Bin harnesses the power of renewable energy to ensure uninterrupted operation and sustainability. Integrated with precision, the solar panels efficiently capture sunlight, converting it into electricity to power the bin's monitoring systems and communication modules. This eco-friendly approach not only reduces reliance on traditional energy sources but also enhances the bin's autonomy and resilience, contributing to a greener and more efficient waste management ecosystem.

      the ESP32 typically operates within a voltage range of 2.2V to 3.6V, which can be efficiently supplied by a solar panel system. The solar panel converts sunlight into electrical power, which is then regulated and stored in a battery by a charging module. This stored energy can effectively power the ESP32 and its associated components, ensuring continuous operation even in areas with limited access to traditional power sources.

      To elevate the voltage from the battery to the required level for the ESP32, a DC-DC booster is linked to the charging module. The current regulation is achieved through a potentiometer resistor integrated with the voltage booster. Subsequently, this regulated power supply is directed to the ESP32, ensuring optimal performance and stability.

      At a specific voltage threshold, the ESP32 initiates its pre-programmed sequence to establish a

      connection with the Wi-Fi network. This firmware, already embedded within the ESP32's memory, enables seamless integration with the designated network, facilitating data transmission and communication functionalities.

      The ultrasonic sensor, interfaced with the ESP32, commences the process of gauging the garbage level within the bin. This sensor utilizes sound waves to accurately measure the distance to the surface of the garbage, providing crucial data for determining the fill level of the bin.
